FIELD Embodiments described herein relate generally to a light emitting device. BACKGROUND White LED light emitting devices that emit white light by combining a fluorescer with a semiconductor light emitting element such as a blue LED have been developed as small light emitting devices having low power consumption. JP-A 2001-210874 (Kokai) discusses a configuration in which an LED chip including a substrate and a fluorescer layer provided beforehand on the lower face of the substrate is mounted on a leadframe and a fluorescer is coated onto the surface of the LED chip. However, the efficiency cannot be increased sufficiently for such a configuration. Further, the heat dissipation is poor because the fluorescer layer and a die bonding adhesive are provided between the LED chip and the leadframe; the luminous efficacy decreases due to heat generation; and the reliability undesirably decreases. Despite the increasing need for higher efficiency of light emitting devices, the efficiency cannot be increased sufficiently by conventional art.

DETAILED DESCRIPTION In general, according to one embodiment, a light emitting device includes a semiconductor light emitting element, a mounting member, a first wavelength conversion layer, and a first transparent layer. The semiconductor light emitting element emits a first light. The semiconductor light emitting element is placed on the mounting member. The first wavelength conversion layer is provided between the semiconductor light emitting element and the mounting member in contact with the mounting member. The first wavelength conversion layer absorbs the first light and emits a second light having a wavelength longer than a wavelength of the first light. The first transparent layer is provided between the semiconductor light emitting element and the first wavelength conversion layer in contact with the semiconductor light emitting element and the first wavelength conversion layer. The first transparent layer is transparent to the first light and the second light. Exemplary embodiments of the invention will now be described in detail with reference to the drawings. The drawings are schematic or conceptual; and the relationships between the thickness and width of portions, the proportions of sizes among portions, etc., are not necessarily the same as the actual values thereof. Further, the dimensions and proportions may be illustrated differently among drawings, even for identical portions. In the specification and drawings of the application, components similar to those described in regard to a drawing thereinabove are marked with like reference numerals, and a detailed description is omitted as appropriate. First Embodiment FIG. 1 is a schematic cross-sectional view illustrating the configuration of a light emitting device according to a first embodiment of the invention. FIG. 2 is a schematic cross-sectional view illustrating the configuration of a semiconductor light emitting element used in the light emitting device according to the first embodiment of the invention. As illustrated in FIG. 1 , the light emitting device 210 according to this embodiment includes the semiconductor light emitting element 10 , a mounting member 20 , a first wavelength conversion layer 30 and a first transparent layer 40 . The first wavelength conversion layer 30 is provided between the semiconductor light emitting element 10 and the mounting member 20 in contact with the mounting member 20 . The first wavelength conversion layer 30 absorbs a first light emitted from the semiconductor light emitting element 10 and emits a second light having a wavelength longer than the wavelength of the first light. In other words, the wavelength band of the second light is longer than the wavelength band of the first light. For example, the shortest wavelength of the wavelength band of the second light is longer than the shortest wavelength of the wavelength band of the first light. For example, the longest wavelength of the wavelength band of the second light is longer than the longest wavelength of the wavelength band of the first light. For example, the shortest wavelength of the wavelength band of the second light is longer than the longest wavelength of the wavelength band of the first light. For example, the peak wavelength of the second light is longer than the peak wavelength of the first light. The first transparent layer 40 is provided between the semiconductor light emitting element 10 and the first wavelength conversion layer 30 in contact with the semiconductor light emitting element 10 and the first wavelength conversion layer 30 . The first transparent layer 40 is transparent to the first light and the second light. As illustrated in FIG. 2 , the semiconductor light emitting element 10 includes a stacked structural body including a buffer layer 101 , an n-type contact layer 102 , a light emitting layer 103 , a p-type electron blocking layer 104 , and a p-type contact layer 105 stacked sequentially on a substrate 90 . The buffer layer 101 may include, for example, polycrystalline GaN; and the n-type contact layer 102 may include, for example, GaN doped with Si. The light emitting layer 103 may have, for example, a quantum well structure in which a barrier layer and a well layer are multiply stacked alternately. The barrier layer may include, for example, GaN; and the well layer may include, for example, InGaN. The p-type electron blocking layer 104 may include, for example, AlGaN doped with Mg. The p-type contact layer 105 may include, for example, GaN doped with Mg. In the stacked structural body of the semiconductor light emitting element 10 of this specific example, a portion of the n-type contact layer 102 and a portion of the light emitting layer 103 , the p-type electron blocking layer 104 , and the p-type contact layer 105 are removed; and a portion of the n-type contact layer 102 is exposed. An n-side electrode 108 is further provided to connect to the n-type contact layer 102 ; and a p-side electrode 107 is further provided to connect to the p-type contact layer 105 . In other words, the p-side electrode 107 is provided on a first major surface 10 a of the semiconductor light emitting element 10 on the p-type semiconductor layer (the p-type contact layer 105 ) side in contact with the p-type semiconductor layer (the p-type contact layer 105 ). A second major surface 10 b of the semiconductor light emitting element 10 on the n-type semiconductor layer (the n-type contact layer 102 ) side is the face on the side opposing the mounting member 20 . Each of the semiconductor layers of the semiconductor light emitting element 10 may include a nitride semiconductor. In other words, the semiconductor light emitting element 10 may include, for example, a blue light emitting diode (LED), a bluish-violet LED, a violet LED, an ultraviolet LED, etc. However, the embodiments of the invention are not limited thereto. Any semiconductor light emitting element 10 may be used. In this specific example as illustrated in FIG. 1 , a p-side substrate electrode 107 e and an n-side substrate electrode 108 e are provided on the mounting member 20 . The p-side substrate electrode 107 e and the n-side substrate electrode 108 e are connected to the p-side electrode 107 and the n-side electrode 108 of the semiconductor light emitting element 10 via a p-side interconnect 107 w and an n-side interconnect 108 w , respectively. However, the description recited above is one example; and the embodiments of the invention are not limited thereto. Various modifications of the form of the electrical connections and the dispositions of the semiconductor light emitting element 10 and the mounting member 20 are possible. Although the mounting member 20 is a member having a cup-like configuration on which the semiconductor light emitting element 10 is mounted in this specific example, it is sufficient for the mounting member 20 to be a component on which the semiconductor light emitting element 10 can be mounted. The configuration of the mounting member 20 is arbitrary. The mounting member 20 may include any material such as an inorganic material, an organic material, etc. The face of the mounting member 20 on the semiconductor light emitting element 10 side (the first wavelength conversion layer 30 side) may be a face having a high reflectance. For example, a reflective film (not illustrated) made of Ag, etc., may be provided on the face of the mounting member 20 on the semiconductor light emitting element 10 side, that is, on the mounting face of the mounting member 20 (the face on which the semiconductor light emitting element 10 is mounted). The first wavelength conversion layer 30 may include a first wavelength conversion particle 31 dispersed in a first resin 32 , where the first wavelength conversion particle 31 absorbs the first light and emits the second light. The first wavelength conversion particle 31 may include, for example, a fluorescer fine particle, a nitride semiconductor fine particle, etc. The nitride semiconductor may include Al x Ga y In 1-x-y N (0≦x≦1, 0≦y≦1, and x+y≦1). For such a nitride semiconductor, the wavelength of the emitted light can be changed by changing the values of x and y recited above. In the nitride semiconductor recited above, a portion of the Group III elements may be replaced with B, Tl, etc. A portion of N may be replaced with P, As, Sb, Bi, etc. The first wavelength conversion particle 31 is not limited to one type of material and may include two or more types of materials. For example, a silicone-based resin, etc., may be used as the first resin 32 of the first wavelength conversion layer 30 . The first wavelength conversion layer 30 may have a bonding function of bonding the semiconductor light emitting element 10 to the mounting member 20 via the first transparent layer 40 . In other words, a material having a bonding function may be used as the first resin 32 . Thereby, the semiconductor light emitting element 10 (and the first transparent layer 40 ) can be fixed to the mounting member 20 without providing a separate bonding agent; a decrease of the luminous efficacy caused by separately providing the bonding agent can be suppressed; and the processes can be simplified. The first transparent layer 40 may include any material transparent to the first and second light. In other words, the first transparent layer 40 is substantially transparent to wavelengths near the light emission wavelength of the semiconductor light emitting element 10 and wavelengths in wavelength regions longer thereto. The first transparent layer 40 may include, for example, any organic material such as a silicone-based resin and any inorganic material including oxides such as SiO 2 , nitrides such as SiN, and oxynitrides such as SiON. FIG. 3 is a schematic view illustrating operations of the light emitting device according to the first embodiment of the invention. As illustrated in FIG. 3 , a portion of a first light L 1 emitted by the light emitting layer 103 of the semiconductor light emitting element 10 travels toward the first major surface 10 a (the upper face) on the p-type semiconductor layer side and is extracted to the outside of the light emitting device 210 . One other portion of the first light L 1 travels toward the second major surface 10 b (the lower face) on the n-type semiconductor layer (the n-type contact layer 102 ) side, passes through the first transparent layer 40 , and enters the first wavelength conversion layer 30 . The first light L 1 is absorbed in the first wavelength conversion layer 30 ; and a second light L 2 having a wavelength characteristic different from that of the first light (a wavelength characteristic having a wavelength longer than that of the first light L 1 ) is emitted. In the case where the first wavelength conversion layer 30 is not provided, the efficiency decreases because the first light L 1 emitted from the semiconductor light emitting element 10 to the mounting member 20 side is reflected by the mounting member 20 , returns to the interior of the semiconductor light emitting element 10 , and is undesirably reabsorbed particularly by the light emitting layer 103 of the semiconductor light emitting element 10 . Conversely, by providing the first wavelength conversion layer 30 , the first light L 1 emitted from the semiconductor light emitting element 10 to the mounting member 20 side is converted into the second light L 2 having a wavelength longer than that of the first light L 1 . Thereby, the second light L 2 is not easily reabsorbed by the semiconductor light emitting element 10 (particularly the light emitting layer 103 ) because the wavelength of the second light L 2 is longer than that of the first light L 1 even in the case where the second light L 2 is reflected by the mounting member 20 , returns to the interior of the semiconductor light emitting element 10 , and enters the semiconductor light emitting element 10 (particularly the light emitting layer 103 ). Therefore, the second light L 2 is easily emitted from the semiconductor light emitting element 10 to the outside; and losses are low. By providing the first transparent layer 40 in the light emitting device 210 according to this embodiment, the light reflected by the mounting member 20 is emitted directly to the outside without returning to the semiconductor light emitting element 10 ; and the light extraction efficiency increases further. In other words, the second light L 2 emitted by the first wavelength conversion layer 30 enters the first transparent layer 40 prior to being incident on the semiconductor light emitting element 10 . Then, the second light L 2 propagates through the first transparent layer 40 and is extracted from the side face of the first transparent layer 40 to the external environment. For example, the second light L 2 propagates through the first transparent layer 40 by being reflected by the interface between the first transparent layer 40 and the second major surface 10 b on the first transparent layer 40 side of the semiconductor light emitting element 10 and the interface between the first transparent layer 40 and the first wavelength conversion layer 30 or by being reflected by the interface between the first transparent layer 40 and the second major surface 10 b and the interface between the first wavelength conversion layer 30 and the mounting member 20 . Thereby, the second light L 2 substantially does not enter the interior (particularly the light emitting layer 103 ) of the semiconductor light emitting element 10 ; and the loss due to the second light L 2 being absorbed in the interior (particularly the light emitting layer 103 ) of the semiconductor light emitting element 10 is suppressed. Thereby, the efficiency increases further. The first light L 1 emitted from the semiconductor light emitting element 10 also may propagate through the first transparent layer 40 to be extracted from the side face of the first transparent layer 40 to the external environment. For example, the first light L 1 propagates through the first transparent layer 40 by being reflected by the interface between the first transparent layer 40 and the second major surface 10 b on the first transparent layer 40 side of the semiconductor light emitting element 10 and the interface between the first transparent layer 40 and the first wavelength conversion layer 30 or by being reflected by the interface between the first transparent layer 40 and the second major surface 10 b and the interface between the first wavelength conversion layer 30 and the mounting member 20 . Thereby, the first light L 1 substantially does not enter the interior (particularly the light emitting layer 103 ) of the semiconductor light emitting element 10 from the mounting member 20 side; and the loss due to the first light L 1 being absorbed in the interior (particularly the light emitting layer 103 ) of the semiconductor light emitting element 10 is suppressed. Thereby, the efficiency increases. To promote the first light L 1 and the second light L 2 propagating through the interior of the first transparent layer 40 , it is desirable to appropriately set the refractive indexes of the first transparent layer 40 , the first wavelength conversion layer 30 , and the semiconductor light emitting element 10 (particularly the portion on the first transparent layer 40 side). In other words, it is desirable for the refractive index (a first refractive index n 1 ) of the portion of the semiconductor light emitting element 10 contacting the first transparent layer 40 (i.e., the portion on the second major surface 10 b side, and in this specific example, the substrate 90 ) to be higher than the refractive index (a second refractive index n 2 ) of the first transparent layer 40 . It is desirable for the refractive index (a third refractive index n 3 ) of the portion of the first wavelength conversion layer 30 contacting the first transparent layer 40 to be not higher than the refractive index (the second refractive index n 2 ) of the first transparent layer 40 . In other words, it is desirable that n 3 ≦n 2 <n 1 . By setting the first refractive index n 1 higher than the second refractive index n 2 , the second light L 2 traveling from the first transparent layer 40 toward the semiconductor light emitting element 10 can be reflected efficiently to the first transparent layer 40 side. Further, the first light L 1 entering the first transparent layer 40 can propagate efficiently through the first transparent layer 40 . By setting the third refractive index n 3 to be not higher than the second refractive index n 2 , the second light L 2 efficiently enters the first transparent layer 40 from the first wavelength conversion layer 30 . Further, the second light L 2 from the first transparent layer 40 travelling toward the first wavelength conversion layer 30 can be reflected by the interface between the first transparent layer 40 and the first wavelength conversion layer 30 ; and the second light L 2 can propagate efficiently through the first transparent layer 40 . In the case where the third refractive index n 3 is equal to the second refractive index n 2 , the first light L 1 travelling from the first transparent layer 40 toward the first wavelength conversion layer 30 passes through the interface between the first transparent layer 40 and the first wavelength conversion layer 30 without loss; and the first wavelength conversion layer 30 efficiently emits the second light L 2 . Also, the second light L 2 reflected by the face of the mounting member 20 on the first wavelength conversion layer 30 side can efficiently enter the first transparent layer 40 ; and the second light L 2 can efficiently propagate through the first transparent layer 40 . Further, the first light L 1 entering the first transparent layer 40 can efficiently propagate through the first transparent layer 40 . For example, in this specific example, sapphire is used as the substrate 90 which is the portion of the semiconductor light emitting element 10 on the side contacting the first transparent layer 40 (the second major surface 10 b side). In such a case, the first refractive index n 1 is about 1.8. In the case where the portion of the semiconductor light emitting element 10 on the side contacting the first transparent layer 40 (the second major surface 10 b side) is the n-type contact layer 102 (e.g., a GaN layer), the first refractive index n 1 is about 2.5. On the other hand, a silicone-based resin, for example, may be used as the first transparent layer 40 ; and the second refractive index n 2 may be about 1.5. The first wavelength conversion layer 30 may include the first wavelength conversion particles 31 dispersed in the first resin 32 ; a silicone-based resin may be used as the first resin 32 ; and the third refractive index n 3 may be about 1.4. Thus, the relationship n 3 ≦n 2 <n 1 can be realized. By setting the refractive indexes to such a relationship, the first light L 1 and the second light L 2 are efficiently reflected (e.g., undergo total internal reflections) by the interface on the semiconductor light emitting element 10 side of the first transparent layer 40 and the interface on the first wavelength conversion layer 30 side of the first transparent layer 40 . Thereby, the first light L 1 and the second light L 2 can efficiently propagate through the first transparent layer 40 ; such light can be emitted to the outside without entering the semiconductor light emitting element 10 ; the light extraction efficiency can be increased; and the efficiency can be increased. Thus, the efficiency increases further by controlling the mutual relationship between the first refractive index n 1 , the second refractive index n 2 , and the third refractive index n 3 . It is desirable for the particle size of the first wavelength conversion particle 31 to be not less than 1 micrometer (μm) and not more than 50 μm. In the case where the particle size of the first wavelength conversion particle 31 is not less than 1 μm and not more than 50 μm, the wavelength conversion efficiency of the first wavelength conversion layer 30 increases; and the luminous efficacy increases. In the case where the particle size of the first wavelength conversion particle 31 is less than 1 μm, the absorbency index of the first light L 1 in the first wavelength conversion layer 30 decreases; and the luminous efficacy easily decreases. In the case where the particle size of the first wavelength conversion particle 31 is greater than 50 μm, the heat dissipation is poor; and the luminous efficacy may decrease. In some cases, the bonding strength of the first wavelength conversion layer 30 may decrease; and the reliability of the light emitting device may deteriorate. The first wavelength conversion layer 30 may include multiple layers. For example, the first wavelength conversion layer 30 may include, for example, a red fluorescer layer including a red fluorescer and a yellow fluorescer layer including a yellow fluorescer stacked on the red fluorescer layer. The first wavelength conversion layer 30 may further include a transparent layer provided between the yellow fluorescer layer recited above and the red fluorescer layer recited above. Thereby, both the optical characteristics and the ease of manufacturing can be improved further. First Example Characteristics of a light emitting device of a first example according to this embodiment will now be described compared to a comparative example. The light emitting device 210 a of the first example has a configuration similar to the configuration of the light emitting device 210 illustrated in FIG. 1 . The light emitting device 210 a was constructed as follows. A mounting substrate made of AlN was used as the mounting member 20 . In other words, the mounting member 20 was constructed by molding an AlN material. On the other hand, a blue LED chip having a light emitting layer 103 including an InGaN compound semiconductor was used as the semiconductor light emitting element 10 . The peak of the light emission wavelength (the wavelength of the first light L 1 ) of the semiconductor light emitting element 10 was 450 nm (nanometers). The first transparent layer 40 was formed on the lower face (the second major surface 10 b ) of the semiconductor light emitting element 10 . A transparent silicone resin was used as the first transparent layer 40 . In other words, the first transparent layer 40 was obtained by coating a silicone resin on the lower face (the second major surface 10 b ) of the semiconductor light emitting element 10 and drying the silicone resin at 150° C. for 10 minutes to 90 minutes at atmospheric pressure. The refractive index (the second refractive index n 2 ) of the silicone resin was 1.54 which was higher than the refractive index (the third refractive index n 3 ) of 1.41 of the first wavelength conversion layer 30 described below and less than the refractive index (the first refractive index n 1 ) of 1.78 of the substrate 90 of the semiconductor light emitting element 10 . On the other hand, the first wavelength conversion layer 30 was formed on the mounting face of the mounting member 20 . A silicate-based yellow fluorescer (having a composition of (Sr, Ca, Ba) 2 SiO 4 :Eu) having a light emission peak at 560 nm was used as the first wavelength conversion particle 31 of the first wavelength conversion layer 30 . A silicone-based transparent die bonding material was used as the first resin 32 . The first wavelength conversion particle 31 having a particle size of about 10 μm was dispersed in the first resin 32 with a concentration of 50 wt % (weight percent) and then coated onto the mounting face of the mounting member 20 to form the first wavelength conversion layer 30 . The semiconductor light emitting element 10 was bonded to the mounting member 20 by the first wavelength conversion layer 30 and fixed by placing the semiconductor light emitting element 10 including the first transparent layer 40 on the first wavelength conversion layer 30 and drying the first wavelength conversion layer 30 . Subsequently, the p-side substrate electrode 107 e and the n-side substrate electrode 108 e of the mounting member 20 were electrically connected to the p-side electrode 107 and the n-side electrode 108 of the semiconductor light emitting element 10 by the p-side interconnect 107 w and the n-side interconnect 108 w , respectively. Thus, the light emitting device 210 a of the first example was constructed. The light emission characteristic of the light emitting device 210 a was measured. The luminous efficacy was 40.7 (lm/W) when driven by a current of 20 mA; and a high efficiency was obtained. First Comparative Example FIG. 4 is a schematic cross-sectional view illustrating the configuration of the light emitting device of a first comparative example. In the light emitting device 219 a of the first comparative example as illustrated in FIG. 4 , the first wavelength conversion layer 30 was provided in contact with the second major surface 10 b of the semiconductor light emitting element 10 ; and a silicone-based transparent die bonding material layer 41 was provided between the first wavelength conversion layer 30 and the mounting member 20 . The silicone-based transparent die bonding material layer 41 was a layer having characteristics similar to those of the first transparent layer 40 of the first example. In other words, the light emitting device 219 a had a configuration in which the position of the first wavelength conversion layer 30 and the position of the first transparent layer 40 of the light emitting device 210 a of the first example are interchanged with each other. The light emitting device 219 a having such a configuration had a luminous efficacy of 38.2 (lm/W) when driven by a current of 20 mA; and a low efficiency was obtained. Second Comparative Example FIG. 5 is a schematic cross-sectional view illustrating the configuration of a light emitting device of a second comparative example. In the light emitting device 219 b of the second comparative example as illustrated in FIG. 5 , the first transparent layer 40 is not provided. In other words, the light emitting device 219 b corresponds to a configuration in which the first transparent layer 40 is not provided in the light emitting device 210 a of the first example. The light emitting device 219 b having such a configuration had a luminous efficacy of 38.8 (lm/W) when driven by a current of 20 mA. Although the efficiency was improved from the light emitting device 219 a of the first comparative example, the degree of the improvement (the ratio to that of the first comparative example) was about 1.02; and the degree of the improvement was low. Conversely, as described above, the luminous efficacy of the light emitting device 210 a of the first example was higher than those of the first comparative example and the second comparative example. Further, the degree of the improvement of the efficiency in the first example (the ratio to that of the first comparative example) was about 1.06; and the degree of the improvement of the first example was extremely high. It is considered that the efficiency of the first comparative example was low because the first wavelength conversion layer 30 directly contacts the semiconductor light emitting element 10 , the second light L 2 emitted by the first wavelength conversion layer 30 is not easily extracted directly to the outside, and much of the second light L 2 enters the semiconductor light emitting element 10 and is undesirably absorbed in the interior of the semiconductor light emitting element 10 . Further, because the silicone-based transparent die bonding material layer 41 is provided between the first wavelength conversion layer 30 and the mounting member 20 , the heat generated by the semiconductor light emitting element 10 and the first wavelength conversion layer 30 is not easily conducted to the mounting member 20 and is not easily dissipated. It is considered that the temperature of the semiconductor light emitting element 10 thereby increases easily, the luminous efficacy of the semiconductor light emitting element 10 decreases, and the efficiency decreases further. In the second comparative example as well, it is considered that the efficiency was low because the first wavelength conversion layer 30 directly contacts the semiconductor light emitting element 10 , the second light L 2 emitted by the first wavelength conversion layer 30 is not easily extracted directly to the outside, and much of the second light L 2 enters the semiconductor light emitting element 10 and is undesirably absorbed in the interior of the semiconductor light emitting element 10 . It is considered that the efficiency of the second comparative example was higher than that of the first comparative example because the first wavelength conversion layer 30 directly contacts the mounting member 20 , the heat generated in the first wavelength conversion layer 30 is easily conducted to the mounting member 20 , the heat generation is suppressed, and the temperature increase of the semiconductor light emitting element 10 is suppressed. Conversely, by providing the first transparent layer 40 between the semiconductor light emitting element 10 and the first wavelength conversion layer 30 in the light emitting device 210 a of the first example, the light (the first light L 1 and the second light L 2 ) reflected by the mounting member 20 can be emitted directly to the outside without returning to the semiconductor light emitting element 10 ; and the light extraction efficiency increases. Additionally, the first wavelength conversion layer 30 directly contacts the mounting member 20 . Therefore, the heat generated in the first wavelength conversion layer 30 is conducted efficiently to the mounting member 20 ; the heat generation is suppressed; the temperature increase of the semiconductor light emitting element 10 is suppressed; the luminous efficacy decrease of the semiconductor light emitting element 10 is suppressed; and the luminous efficacy increases. Thus, the form of the light emitting device 210 according to the first embodiment can be applied to the light emitting device 210 a of the first example to provide a light emitting device having a high efficiency. In the light emitting device 219 a of the first comparative example, the fluorescer layer easily peels from the semiconductor light emitting element 10 and uneven color and luminance fluctuation of the light emission undesirably may occur in the case where element separation is performed and the fluorescer layer used to form the first wavelength conversion layer 30 is formed beforehand on the lower face of the substrate 90 of the semiconductor light emitting element 10 prior to the element separation. The light emitting devices 210 a , 219 a , and 219 b recited above were adjusted not to white light but to blue light assuming that the second wavelength conversion layer described below is to be further disposed. In other words, the chromaticity coordinates of the light emission wavelength of the light emitting devices 210 a , 219 a , and 219 b were (0.18, 0.10). For the light emissions of the same chromaticity, the light emitting device 210 a of the first example realized an efficiency higher than those of the light emitting devices 219 a and 219 b of the first comparative example and the second comparative example as recited above. Second Embodiment FIG. 6 is a schematic cross-sectional view illustrating the configuration of a light emitting device according to a second embodiment of the invention. As illustrated in FIG. 6 , the light emitting device 220 according to this embodiment further includes a second wavelength conversion layer 80 and a second transparent layer 60 in addition to the semiconductor light emitting element 10 , the mounting member 20 , the first wavelength conversion layer 30 , and the first transparent layer 40 recited above. The second wavelength conversion layer 80 is provided on the side of the semiconductor light emitting element 10 opposite to the first transparent layer 40 . The second wavelength conversion layer 80 absorbs the first light L 1 and emits a third light having a wavelength characteristic different from that of the first light L 1 . The third light may have a wavelength characteristic different from that of the second light L 2 ; and the third light may have substantially the same wavelength characteristic as the second light L 2 . The second wavelength conversion layer 80 further absorbs the second light L 2 ; and the third light thereby emitted from the second wavelength conversion layer 80 may have a wavelength characteristic different from those of the first light L 1 and the second light L 2 . The second transparent layer 60 is provided between the semiconductor light emitting element 10 and the second wavelength conversion layer 80 . The second transparent layer 60 is transparent to the first light L 1 , the second light L 2 , and the third light. In other words, a transparent resin layer, for example, may be provided as the second transparent layer 60 with, for example, an exterior surface having a curved configuration protruding upward to cover the semiconductor light emitting element 10 . A silicone resin, for example, may be used as the second transparent layer 60 . The curve of the cross section of the curved surface having the upward protruding configuration may have any configuration such as, for example, a semicircular arc-like configuration, a parabolic configuration, etc. In this specific example, the end portion of the second transparent layer 60 contacts the mounting member 20 . Thus, by providing the second transparent layer 60 to cover the semiconductor light emitting element 10 , the second transparent layer 60 can protect the semiconductor light emitting element 10 ; and the reliability of the light emitting device 220 increases. However, the embodiments of the invention are not limited thereto. In some cases, at least a portion of the end portion of the second transparent layer 60 may be provided apart from the mounting member 20 . The second wavelength conversion layer 80 is provided on the second transparent layer 60 . The second wavelength conversion layer 80 may include a second wavelength conversion particle (not illustrated) and a second resin (not illustrated) in which the second wavelength conversion particle is dispersed. For example, the second wavelength conversion layer 80 may include a fluorescer particle and a resin (the second resin) in which the fluorescer particle is dispersed. The second wavelength conversion particle is not limited to one type of material and may include two or more types of materials. The light emission characteristic (e.g., the light emission wavelength) of the third light emitted by the second wavelength conversion layer 80 may be set appropriately based on the light emission characteristic (e.g., the light emission wavelength) of the first light L 1 emitted by the semiconductor light emitting element 10 and the light emission characteristic (e.g., the light emission wavelength) of the second light L 2 emitted by the first wavelength conversion layer 30 . The second wavelength conversion layer 80 generates heat in the case where light (the third light) is emitted in the second wavelength conversion layer 80 . In the comparative examples in which the second wavelength conversion layer 80 is provided directly around the semiconductor light emitting element 10 , the temperature of the semiconductor light emitting element 10 increases due to the heat generation of the second wavelength conversion layer 80 ; and the luminous efficacy of the semiconductor light emitting element 10 decreases. Conversely, in the light emitting device 220 according to this embodiment, the second transparent layer 60 is provided to cover the semiconductor light emitting element 10 and the second wavelength conversion layer 80 is provided thereon. Therefore, even in the case where the second wavelength conversion layer 80 generates heat, the conduction of the heat between the second wavelength conversion layer 80 and the semiconductor light emitting element 10 is suppressed; the increase of the temperature of the semiconductor light emitting element 10 can be suppressed; and a high value of the luminous efficacy of the semiconductor light emitting element 10 can be maintained. In other words, the light emitting device 220 can increase the efficiency by causing light (the first light L 1 and the second light L 2 ) to be guided to the outside by the first transparent layer 40 while suppressing the decrease of the efficiency due to the light being reflected by the mounting member 20 to return to the interior of the semiconductor light emitting element 10 and be reabsorbed by the light emitting layer 103 of the semiconductor light emitting element 10 because the first wavelength conversion layer 30 converts the first light L 1 into the second light L 2 having a wavelength longer than that of the first light L 1 . Further, by providing the second transparent layer 60 between the second wavelength conversion layer 80 and the semiconductor light emitting element 10 , the temperature increase of the semiconductor light emitting element 10 due to the heat generation during the wavelength conversion of the second wavelength conversion layer 80 can be suppressed; and the decrease of the luminous efficacy due to the temperature increase of the semiconductor light emitting element 10 can be suppressed. Also, by providing the second transparent layer 60 between the second wavelength conversion layer 80 and the semiconductor light emitting element 10 , the film thickness of the second wavelength conversion layer 80 can be easily adjusted; and the reabsorption of the second light L 2 in the second wavelength conversion layer 80 can be suppressed by optimally adjusting the film thickness. Thereby, a light emitting device having a high luminous efficacy can be obtained. The end portion of the second wavelength conversion layer 80 can be provided, for example, to contact the mounting member 20 . Thereby, the heat generated by the second wavelength conversion layer 80 can be conducted efficiently to the mounting member 20 ; the temperature increase of the semiconductor light emitting element 10 can be decreased further; the luminous efficacy of the semiconductor light emitting element 10 can be increased; and the efficiency of the light emitting device 220 can be increased further. However, the embodiments of the invention are not limited thereto. At least a portion of the end portion of the second wavelength conversion layer 80 may be provided apart from the mounting member 20 in the case where little heat is generated by the second wavelength conversion layer 80 , in the case where the temperature of the semiconductor light emitting element 10 does not increase easily, in the case where the luminous efficacy does not decrease easily even when the temperature of the semiconductor light emitting element 10 increases, etc. The second transparent layer 60 may include a layer including a gas (including air). Thereby, the heat generated by the second wavelength conversion layer 80 is not easily conducted to the semiconductor light emitting element 10 ; and the efficiency increases. In the case where the second transparent layer 60 is a gas (including air) layer, for example, the second wavelength conversion layer 80 may be formed using a die and the like such that the second wavelength conversion layer 80 maintains its own shape; and the formed second wavelength conversion layer 80 can be disposed on the semiconductor light emitting element 10 to cover the semiconductor light emitting element 10 . By multiply providing wavelength conversion layers such as the first wavelength conversion layer 30 and the second wavelength conversion layer 80 , it is easier to control the wavelength characteristic of the light emitted by the light emitting device 220 ; and it is easier to realize the desired light emission with a high color rendition. In the light emitting device 220 according to this embodiment, the wavelength of the third light is longer than the wavelength of the first light L 1 and not longer than the wavelength of the second light L 2 . The wavelength band of the third light is longer than the wavelength band of the first light L 1 and not longer than the wavelength band of the second light L 2 . For example, the shortest wavelength of the wavelength band of the third light is longer than the shortest wavelength of the wavelength band of the first light L 1 . For example, the longest wavelength of the wavelength band of the third light is longer than the longest wavelength of the wavelength band of the first light L 1 . For example, the shortest wavelength of the wavelength band of the third light is longer than the longest wavelength of the wavelength band of the first light L 1 . Further, for example, the shortest wavelength of the wavelength band of the third light is not longer than the shortest wavelength of the wavelength band of the second light L 2 . For example, the longest wavelength of the wavelength band of the third light is not longer than the longest wavelength of the wavelength band of the second light L 2 . The longest wavelength of the wavelength band of the third light may be equal to or shorter than the shortest wavelength of the wavelength band of the second light L 2 . Because the wavelength of the third light is longer than the wavelength of the first light L 1 , the reabsorption of the third light by particularly the light emitting layer 103 of the semiconductor light emitting element 10 is suppressed; and the efficiency increases. In the case where the wavelength of the second light L 2 is shorter than the wavelength of the third light, the second light L 2 is absorbed by the second wavelength conversion layer when the second light L 2 passes through the second wavelength conversion layer 80 ; and the efficiency easily decreases. However, by providing the third light with a wavelength not longer than the wavelength of the second light L 2 , the absorption of the second light L 2 in the second wavelength conversion layer 80 is suppressed; and the efficiency increases. For example, in the case where the first light L 1 is blue light, the second light L 2 may be yellow light and the third light also may be yellow light. Also, for example, in the case where the first light L 1 is blue light, the second light L 2 may be red light and the third light may be green light. In the case where, for example, the first light L 1 is near-ultraviolet light, the second light L 2 may be red light and the third light may be blue and green light. For example, in the case where the first light L 1 emitted from the semiconductor light emitting element 10 is light having a light emission peak in the blue region, the first wavelength conversion layer 30 emits a yellow second light L 2 (e.g., a fluorescence); and the second wavelength conversion layer 80 also emits a yellow third light. Thereby, the light emitting device 220 can emit a white light. Also, in the case where the first light L 1 emitted from the semiconductor light emitting element 10 is light having a light emission peak in the blue region, the first wavelength conversion layer 30 emits a red second light L 2 (e.g., a fluorescence); and the second wavelength conversion layer 80 emits a green third light. Thereby, the light emitting device 220 emits light of the three colors of red, green, and blue and can emit white light. In the case where the first light L 1 emitted from the semiconductor light emitting element 10 is light having a light emission peak in the near-ultraviolet region, the first wavelength conversion layer 30 may emit a red second light L 2 (e.g., a fluorescence); and the second wavelength conversion layer 80 may emit a green and blue third light. Thereby, the light emitting device 220 emits light of the three colors of red, green, and blue and can emit white light. Thus, for example, a yellow fluorescer may be used as the first wavelength conversion particle 31 of the first wavelength conversion layer 30 ; and a yellow fluorescer also may be used in the second wavelength conversion layer 80 . Further, for example, a red fluorescer may be used as the first wavelength conversion particle 31 of the first wavelength conversion layer 30 ; and a green fluorescer may be used as the second wavelength conversion particle of the second wavelength conversion layer 80 . Also, a red fluorescer may be used as the first wavelength conversion particle 31 of the first wavelength conversion layer 30 ; and the two types of a blue fluorescer and a green fluorescer may be used as the second wavelength conversion particles of the second wavelength conversion layer 80 . However, the description recited above is an example of a configuration in the case where the light emitting device 220 emits white light. The combination of the light emission characteristics of the first light L 1 , the second light L 2 , and the third light is arbitrary. The light emission characteristics of the first light L 1 , the second light L 2 , and the third light may be appropriately set based on the specifications of the light to be emitted by the light emitting device. For example, in this embodiment, any of a red fluorescer layer, a yellow fluorescer layer, a green fluorescer layer, and a blue fluorescer layer may be used in the first wavelength conversion layer 30 and the second wavelength conversion layer 80 . The red fluorescer layer may emit light in a wavelength region of, for example, 600 nm to 780 nm. The yellow fluorescer layer may emit light in a wavelength region of, for example, 550 nm to 590 nm. The green fluorescer layer may emit light in a wavelength region of, for example, 475 nm to 520 nm. The blue fluorescer layer may emit light in a wavelength region of, for example, 430 nm to 475 nm. The red fluorescer layer may contain, for example, a nitride-based fluorescer of CaAlSiN 3 :Eu or a sialon-based fluorescer. In particular, in the case where a sialon-based fluorescer is used, it is desirable to use (M 1-x ,R x ) a1 AlSi b1 O c1 N d1 Compositional Formula (1) where M is at least one type of metal element excluding Si and Al, and it is particularly desirable for M to be at least one selected from Ca and Sr; R is a light emission center element, and it is particularly desirable for R to be Eu; and x, a1, b1, c1, and d1 satisfy the relationships 0<x≦1, 0.6<a1<0.95, 2<b1<3.9, 0.25<c1<0.45, and 4<d1<5.7. By using the sialon-based fluorescer of Compositional Formula (1), the temperature characteristics of the wavelength conversion efficiency can be improved; and the efficiency in the high current density region can be increased further. The yellow fluorescer layer may contain, for example, a silicate-based fluorescer of (Sr, Ca, Ba) 2 SiO 4 :Eu. The green fluorescer layer may contain, for example, a halophosphate-based fluorescer of (Ba, Ca, Mg) 10 (PO 4 ) 6 .Cl 2 :Eu or a sialon-based fluorescer. In particular, in the case where a sialon-based fluorescer is used, it is favorable to use (M 1-x ,R x ) a2 AlSi b2 O c2 N d2 Compositional Formula (2) where M is at least one type of metal element excluding Si and Al, and it is particularly desirable for M to be at least one selected from Ca and Sr; R is a light emission center element, and it is particularly desirable for R to be Eu; and x, a2, b2, c2, and d2 satisfy the relationships 0<x≦1, 0.93<a2<1.3, 4.0<b2<5.8, 0.6<c2<1, and 6<d2<11. By using the sialon-based fluorescer of Compositional Formula (2), the temperature characteristics of the wavelength conversion efficiency can be improved; and the efficiency in the high current density region can be increased further. The blue fluorescer layer may contain, for example, an oxide-based fluorescer of BaMgAl 10 O 17 :Eu. Any resin regardless of the type may be used as the resins (the first resin 32 and the second resin) used in the first wavelength conversion layer 30 and the second wavelength conversion layer 80 as long as the resin is substantially transparent to the wavelengths near the light emission wavelength of the first light L 1 emitted by the semiconductor light emitting element 10 and wavelengths in wavelength regions longer thereto. Such resins include, for example, silicone resin, epoxy resin, polydimethylsiloxane derivative having an epoxy group, oxetane resin, acrylic resin, cycloolefin resin, urea resin, fluorocarbon resin, polyimide resin, etc. The second wavelength conversion layer 80 may have a configuration in which multiple fluorescer layers having different light emission wavelengths are stacked. In such a case, it is favorable for the multiple fluorescer layers to be stacked such that the fluorescer layers having longer wavelengths are disposed more toward the semiconductor light emitting element 10 side than the fluorescer layers having shorter wavelengths. It is favorable to further provide a third transparent layer on the outer side (the side opposite to the semiconductor light emitting element 10 ) of the second wavelength conversion layer 80 . By providing the third transparent layer, the proportion of the light extracted to the outside increases; and the efficiency increases further. In other words, the reflection and the scattering that occur at the interface between the second wavelength conversion layer 80 and an external medium (e.g., air) due to recesses and protrusions of the fluorescer particles are suppressed; the reabsorption by the second wavelength conversion layer 80 decreases; the proportion of the light extracted to the outside increases; and the efficiency increases. Also, the reliability can be increased by providing the third transparent layer. The third transparent layer may be formed from multiple layers having different refractive indexes. In such a case, it is favorable to stack the layers such that the refractive indexes thereof decrease from the second wavelength conversion layer 80 side toward the outside. Thus, the reflection and the scattering at the interface between the second wavelength conversion layer 80 and the external medium (e.g., air) is suppressed; and the efficiency increases. At least one selected from the first wavelength conversion layer 30 and the second wavelength conversion layer 80 may include multiple layers. For example, the second wavelength conversion layer 80 may include, for example, a green fluorescer layer including a green fluorescer and a blue fluorescer layer including a blue fluorescer stacked on the green fluorescer layer. The second wavelength conversion layer 80 may further include a transparent layer provided between the green fluorescer layer recited above and the blue fluorescer layer recited above. Thereby, both the optical characteristics and the ease of manufacturing can be improved further. Second Example Characteristics of a light emitting device of a second example according to this embodiment will now be described compared to a comparative example. The light emitting device 220 a of the second example has a configuration similar to the configuration of the light emitting device 220 illustrated in FIG. 6 . The light emitting device 220 a was constructed as follows. After constructing the light emitting device 210 a of the first example, a silicone resin layer forming the second transparent layer 60 was formed on the semiconductor light emitting element 10 . In other words, a dispenser was used to coat silicone resin to cover the semiconductor light emitting element 10 while heating the mounting member 20 to a temperature of 150° C. in ambient air at atmospheric pressure. The ratio of the thickness of the silicone resin at the apical portion to the thickness at the end face was substantially 1:1; and the silicone resin was coated in a curved configuration protruding upward. Then, the silicone resin was dried at 150° C. for 60 minutes at atmospheric pressure; and the second transparent layer 60 was formed. On the other hand, a yellow fluorescer dispersion resin forming the second wavelength conversion layer 80 was prepared by dispersing a silicate-based yellow fluorescer (having a composition of (Sr, Ca, Ba) 2 SiO 4 :Eu) in a silicone-based transparent resin. The yellow fluorescer dispersion resin was coated using a dispenser to cover the entire second transparent layer 60 while heating the mounting member 20 to 150° C. at atmospheric pressure in ambient air. The film thickness of the yellow fluorescer dispersion resin was substantially uniform; and the configuration of the yellow fluorescer dispersion resin had a curved configuration protruding upward to conform to the configuration of the second transparent layer 60 . Subsequently, the yellow fluorescer dispersion resin was dried at 150° C. for 60 minutes at atmospheric pressure; and the second wavelength conversion layer 80 was formed. The ratio of the thickness of the second wavelength conversion layer 80 at the apical portion to the thickness at the end face was substantially 1:1. Thus, the light emitting device 220 a of the first example was constructed. The light emitting device 220 a of the first example is an example in which the first light L 1 emitted from the semiconductor light emitting element 10 is blue light and the light emitted from the first wavelength conversion layer 30 and the second wavelength conversion layer 80 (the second light L 2 and the third light) both are yellow light. Third Comparative Example FIG. 7 is a schematic cross-sectional view illustrating the configuration of a light emitting device of a third comparative example. In the light emitting device 229 a of the third comparative example as illustrated in FIG. 7 , the second transparent layer 60 and the second wavelength conversion layer 80 are further provided in the light emitting device 219 a of the first comparative example. In other words, the light emitting device 229 a of the third comparative example has a configuration in which the positions of the first wavelength conversion layer 30 and the first transparent layer 40 in the light emitting device 220 a of the second example are interchanged. Otherwise, the light emitting device 229 a is similar to the light emitting device 220 a of the second example. Fourth Comparative Example FIG. 8 is a schematic cross-sectional view illustrating the configuration of a light emitting device of a fourth comparative example. In the light emitting device 229 b of the fourth comparative example as illustrated in FIG. 8 , the second transparent layer 60 and the second wavelength conversion layer 80 are further provided in the light emitting device 219 b of the second comparative example. In other words, the configuration of the light emitting device 229 b of the fourth comparative example corresponds to the configuration of the light emitting device 220 a of the second example in which the first transparent layer 40 is not provided. Otherwise, the light emitting device 229 b is similar to the light emitting device 220 a of the second example. Fifth Comparative Example FIG. 9 is a schematic cross-sectional view illustrating the configuration of a light emitting device of a fifth comparative example. In the light emitting device 229 c of the fifth comparative example as illustrated in FIG. 9 , the first wavelength conversion layer 30 is not provided while the silicone-based transparent die bonding material layer 41 is provided between the semiconductor light emitting element 10 and the mounting member 20 . The second transparent layer 60 and the second wavelength conversion layer 80 c also are provided. The specifications of a second wavelength conversion layer 80 c of the light emitting device 229 c are adjusted such that the light emission color of the light emitting device 229 c matched the light emission color of the light emitting device 220 a of the second example. In other words, the thickness of the second wavelength conversion layer 80 c of the light emitting device 229 c is thicker than the thickness of the second wavelength conversion layer 80 of the light emitting device 220 a of the second example. The optical characteristics of the light emitting device 220 a of the second example and the light emitting devices 229 a to 229 c of the third to fifth comparative examples such as those recited above were evaluated. The chromaticity coordinates of the light emission color of the light emitting device 220 a and the light emitting devices 229 a to 229 c were (0.34, 0.35); and each of these light emitting devices emitted white light. The light emitting device 220 a of the second example had a luminous efficacy of 87.7 (lm/W) when driven by a current of 20 mA; and a high efficiency was obtained. On the other hand, the light emitting device 229 a of the third comparative example had an efficiency of 83.8 (lm/W) when driven by a current of 20 mA; and a low efficiency was obtained. The light emitting device 229 b of the fourth comparative example had a luminous efficacy of 84.9 (lm/W) when driven by a current of 20 mA which was, while being an improvement from the efficiency of the third comparative example, a low degree of improvement. In other words, the degree of the improvement of the efficiency of the fourth comparative example (the ratio to that of the third comparative example) was about 1.01; and the degree of the improvement was low. The light emitting device 229 c of the fifth comparative example had a luminous efficacy of 80.7 (lm/W) when driven by a current of 20 mA; the efficiency was low; and the efficiency of the fifth example was lower than the efficiency of the third comparative example. Thus, the light emitting device of the second example realized an efficiency higher than those of the light emitting devices 229 a to 229 c of the third to fifth comparative examples. In other words, the degree of the improvement of the light emitting device 220 a of the second example (the ratio to that of the third comparative example) was about 1.05; and the improvement effects of the efficiency were extremely large even compared to the fourth comparative example. It is considered that the efficiency of the fifth comparative example was low because the first wavelength conversion layer 30 was not provided, and therefore the first light L 1 emitted from the semiconductor light emitting element 10 to the mounting member 20 side was reflected by the mounting member 20 , returned to the interior of the semiconductor light emitting element 10 , and was undesirably absorbed particularly in the light emitting layer 103 of the semiconductor light emitting element 10 . Conversely, in the light emitting device 220 a of the second example, the decrease of the efficiency due to the light being reflected by the mounting member 20 to return to the interior of the semiconductor light emitting element 10 and be reabsorbed by particularly the light emitting layer 103 of the semiconductor light emitting element 10 because the first wavelength conversion layer 30 converts the first light L 1 into the second light L 2 is suppressed; the efficiency is increased by the light (the first light L 1 and the second light L 2 ) being guided to the outside by the first transparent layer 40 ; the temperature increase of the semiconductor light emitting element 10 due to the heat generation of the second wavelength conversion layer 80 is suppressed by providing the second transparent layer 60 between the second wavelength conversion layer 80 and the semiconductor light emitting element 10 ; and the decrease of the luminous efficacy of the semiconductor light emitting element 10 is suppressed. Thereby, a light emitting device having a high luminous efficacy is obtained. Thus, the form of the light emitting device 220 according to this embodiment can be applied to the light emitting device 220 a of the second example to provide a light emitting device that emits white light with high efficiency. It is conceivable to use a configuration in which the second transparent layer 60 is not provided and the second wavelength conversion layer 80 is formed directly on the semiconductor light emitting element 10 in the light emitting device 229 a of the fourth comparative example illustrated in FIG. 7 . Such a configuration corresponds to, for example, the configuration discussed in JP-A 2001-210874 (Kokai). In such a configuration, the temperature of the semiconductor light emitting element 10 increases due to the heat generation of the second wavelength conversion layer 80 because the semiconductor light emitting element 10 directly contacts the second wavelength conversion layer 80 ; and the luminous efficacy of the semiconductor light emitting element 10 decreases. Further, it is difficult to adjust the film thickness of the second wavelength conversion layer 80 ; the reabsorption in the second wavelength conversion layer 80 increases; the luminous efficacy decreases; and fluctuation of the luminance and uneven color occur. Accordingly, it is considered that such a configuration has an even lower efficiency than the fourth comparative example. Third Example A light emitting device 230 a of a third example has a configuration similar to that of the light emitting device 220 illustrated in FIG. 6 . However, the light emitting device 230 a of the third example is an example in which the first light L 1 emitted from the semiconductor light emitting element 10 is blue light; the second light L 2 emitted from the first wavelength conversion layer 30 is red light; and the third light emitted from the second wavelength conversion layer 80 is green light. The light emitting device 230 a was constructed as follows. The first transparent layer 40 made of a silicone resin was formed on the lower face (the second major surface 10 b ) of the semiconductor light emitting element 10 by a method similar to that of the first example. On the other hand, the first wavelength conversion layer 30 was formed on the mounting face of the mounting member 20 . A sialon-based red fluorescer (having a composition of Sr 2 Si 7 Al 3 ON 13 :Eu 2+ ) having a light emission peak at 620 nm was used as the first wavelength conversion particle 31 of the first wavelength conversion layer 30 ; and a silicone-based transparent die bonding material was used as the first resin 32 . The first wavelength conversion layer 30 was formed by dispersing the first wavelength conversion particle 31 in the first resin 32 with a concentration of 50 wt % (weight percent) and coating the first resin 32 on the mounting face of the mounting member 20 . Then, the semiconductor light emitting element 10 was bonded to the mounting member 20 and fixed by a method similar to that of the first example; and the p-side substrate electrode 107 e and the n-side substrate electrode 108 e were electrically connected to the p-side electrode 107 and the n-side electrode 108 of the semiconductor light emitting element 10 by the p-side interconnect 107 w and the n-side interconnect 108 w , respectively. Subsequently, after forming the second transparent layer 60 on the semiconductor light emitting element 10 by a method similar to that of the light emitting device 220 a of the second example, a green second wavelength conversion layer 80 was formed on the second transparent layer 60 . In other words, a green fluorescer dispersion resin used to form the second wavelength conversion layer 80 was prepared by dispersing a sialon-based green fluorescer (having a composition of Sr 3 Si 13 Al 3 O 2 N 21 :Eu 2+ ) having a light emission peak at 520 nm in a silicone-based transparent resin. Then, the green fluorescer dispersion resin was coated to cover the entire second transparent layer 60 by a method similar to that of the second example. The film thickness of the green fluorescer dispersion resin was substantially uniform; and the configuration of the green fluorescer dispersion resin was a curved configuration protruding upward to conform to the configuration of the second transparent layer 60 . Subsequently, the second wavelength conversion layer 80 was formed by drying the green fluorescer dispersion resin at 150° C. for 60 minutes at atmospheric pressure. In such a case as well, the ratio of the thickness of the second wavelength conversion layer 80 at the apical portion to the thickness at the end face was substantially 1:1. Sixth Comparative Example The light emitting device 239 b of the sixth comparative example has a configuration in which the first transparent layer 40 is not provided in the light emitting device 230 a of the third example. Otherwise, the light emitting device 239 b is similar to 230 a of the third example. In other words, the configuration of the light emitting device 239 b of the sixth comparative example corresponds to the configuration of the light emitting device 229 b of the fourth comparative example illustrated in FIG. 8 in which a red fluorescer layer containing a sialon-based red fluorescer (having a composition of Sr 2 Si 7 Al 3 ON 13 :Eu 2+ ) was used as the first wavelength conversion layer 30 and a green fluorescer layer containing a sialon-based green fluorescer (having a composition of Sr 3 Si 13 Al 3 O 2 N 21 :Eu 2+ ) was used as the second wavelength conversion layer 80 . Seventh Comparative Example FIG. 10 is a schematic cross-sectional view illustrating the configuration of a light emitting device of a seventh comparative example. In the light emitting device 239 d of the seventh comparative example as illustrated in FIG. 10 , the first wavelength conversion layer 30 is not provided while the silicone-based transparent die bonding material layer 41 is provided between the semiconductor light emitting element 10 and the mounting member 20 . The second transparent layer 60 and the second wavelength conversion layer 80 also are provided. An inner wavelength conversion layer 80 d is provided on the inner side of the second transparent layer 60 ; and an inner transparent layer 60 d is provided between the inner wavelength conversion layer 80 d and the semiconductor light emitting element 10 . A material similar to that used in the second transparent layer 60 of the light emitting device 230 a of the third example was used as the material of the second transparent layer 60 of the light emitting device 239 d of the seventh comparative example. The second wavelength conversion layer 80 of the light emitting device 239 d of the seventh comparative example has specifications similar to those of the second wavelength conversion layer 80 of the light emitting device 230 a of the third example and is a green fluorescer layer containing a sialon-based green fluorescer (having a composition of Sr 3 Si 13 Al 3 O 2 N 21 :Eu 2+ ). On the other hand, a transparent silicone resin similar to that of the first transparent layer 40 of the light emitting device 230 a of the third example was used in the inner transparent layer 60 d of the light emitting device 239 d of the seventh comparative example. A material similar to that of the first wavelength conversion layer 30 of the light emitting device 230 a of the third example was used as the material of the inner wavelength conversion layer 80 d of the light emitting device 239 d of the seventh comparative example; and the inner wavelength conversion layer 80 d was a red fluorescer layer containing a sialon-based red fluorescer (having a composition of Sr 2 Si 7 Al 3 ON 13 :Eu 2+ ). In other words, the configuration of 239 d of the seventh comparative example corresponds to the light emitting device 230 a of the third example in which a red first wavelength conversion layer 30 is provided between a green second wavelength conversion layer 80 and the semiconductor light emitting element 10 . The light emitting device 239 d was constructed as follows. The electrical connections were performed after mounting the semiconductor light emitting element 10 on the mounting member 20 using the silicone-based transparent die bonding material layer 41 ; and the inner transparent layer 60 d was formed by forming a transparent silicone resin using a method similar to that of the second transparent layer 60 . Subsequently, the inner wavelength conversion layer 80 d was formed by forming a red fluorescer layer containing a sialon-based red fluorescer (having a composition of Sr 2 Si 7 Al 3 ON 13 :Eu 2+ ) to cover the inner transparent layer 60 d using a method similar to that of the second wavelength conversion layer 80 . Subsequently, by methods similar to those of the third example, the second transparent layer 60 was formed to cover the inner wavelength conversion layer 80 d ; and the second wavelength conversion layer 80 was formed by forming a green fluorescer layer containing a sialon-based green fluorescer (having a composition of Sr 3 Si 13 Al 3 O 2 N 21 :Eu 2+ ) to cover the second transparent layer 60 . Thus, the light emitting device 239 d of the seventh comparative example illustrated in FIG. 10 was constructed. The optical characteristics of the light emitting device 230 a of the third example and the light emitting devices 239 b and 239 d of the sixth and seventh comparative examples such as those recited above were evaluated. The chromaticity coordinates of the light emission color of the light emitting device 230 a and the light emitting devices 239 b and 239 d were (0.34, 0.35); and each of these light emitting devices emitted white light. The light emitting device 230 a of the third example had a luminous efficacy of 69.4 (lm/W) when driven by a current of 20 mA; and a high efficiency was obtained. On the other hand, the light emitting device 239 b of the sixth comparative example had a luminous efficacy of 66.1 (lm/W) when driven by a current of 20 mA; and the efficiency was low. The light emitting device 239 d of the seventh comparative example had a luminous efficacy of 60.1 (lm/W) when driven by a current of 20 mA; and an even lower efficiency was obtained. Because the first transparent layer 40 is not provided in the light emitting device 239 b of the sixth comparative example, the second light L 2 (the red light) emitted by the red first wavelength conversion layer 30 is not extracted directly to the outside and is emitted to the outside of the semiconductor light emitting element 10 through the semiconductor light emitting element 10 . It is considered that the luminous efficacy decreases because although a portion of the second light L 2 is emitted to the outside of the semiconductor light emitting element 10 , the rest is undesirably trapped and reabsorbed in the interior of the semiconductor light emitting element 10 ; the loss is high; and heat is generated by the reabsorption. In the case of the light emitting device 239 d of the seventh comparative example, the red fluorescer layer of the inner wavelength conversion layer 80 d is disposed proximally to the green fluorescer layer of the second wavelength conversion layer 80 . Therefore, the third light, which is the green fluorescence emitted by the second wavelength conversion layer 80 , is easily absorbed in the inner wavelength conversion layer 80 d . Although the inner wavelength conversion layer 80 d is excited directly by the first light L 1 from the semiconductor light emitting element 10 and can emit light efficiently, the second wavelength conversion layer 80 on the outer side is excited directly by the first light L 1 from the semiconductor light emitting element 10 and by the first light L 1 reflected or scattered by the inner wavelength conversion layer 80 d . Therefore, the efficiency of the light emission of the second wavelength conversion layer 80 decreases by the amount of the loss occurring due to the reflection or the scattering by the inner wavelength conversion layer 80 d . Thereby, it is considered that the efficiency decreases. Further, in the case of the light emitting device 239 d , the first wavelength conversion layer 30 is not provided. Therefore, the first light L 1 emitted from the semiconductor light emitting element 10 toward the mounting member 20 is reflected by the mounting member 20 and again enters the semiconductor light emitting element 10 ; the loss due to the first light L 1 being reabsorbed particularly by the light emitting layer 103 of the semiconductor light emitting element 10 occurs; and the efficiency decreases. On the other hand, in the light emitting device 230 a of the third example in which the first transparent layer 40 is provided, the second light L 2 (the red light) emitted by the red first wavelength conversion layer 30 does not enter the interior of the semiconductor light emitting element 10 , propagates through the first transparent layer 40 , and is extracted directly to the outside; the reabsorption loss due to particularly the light emitting layer 103 of the semiconductor light emitting element 10 is suppressed; heat generation due to the reabsorption is suppressed; and the efficiency increases. In the light emitting device 230 a of the third example, the red fluorescer layer of the first wavelength conversion layer is provided between the semiconductor light emitting element 10 and the mounting member 20 ; and the first wavelength conversion layer 30 is disposed distal to the green fluorescer layer of the second wavelength conversion layer 80 . Therefore, the third light, which is a green fluorescence emitted by the second wavelength conversion layer 80 , substantially does not reach the first wavelength conversion layer 30 . Thereby, the greater part of the green third light emitted by the second wavelength conversion layer 80 is emitted to the outside without being absorbed in the first wavelength conversion layer 30 and the semiconductor light emitting element 10 ; and a high efficiency is obtained. Thus, the form of the light emitting device 220 according to this embodiment can be applied to the light emitting device 230 a of the third example to provide a light emitting device that emits white light with high efficiency. Third Embodiment FIG. 11A , FIG. 11B , and FIG. 11C are schematic cross-sectional views illustrating the configurations of light emitting devices according to a third embodiment of the invention. In a light emitting device 211 according to this embodiment as illustrated in FIG. 11A , the substrate 90 (and the buffer layer 101 ) of the semiconductor light emitting element 10 are removed; the n-type semiconductor layer (the n-type contact layer 102 ) of the semiconductor light emitting element 10 contacts the first transparent layer 40 ; and the first wavelength conversion layer 30 is provided between the first transparent layer 40 and the mounting member 20 . Thus, it is sufficient for the semiconductor light emitting element 10 used in the light emitting devices according to the embodiments of the invention to have a configuration including the light emitting layer 103 provided between an n-type semiconductor layer (e.g., the n-type contact layer 102 ) and a p-type semiconductor layer (e.g., the p-type contact layer 105 ); and the substrate 90 and the like, for example, may be omitted as necessary. In the light emitting device 211 as well, the efficiency is increased by providing the first wavelength conversion layer 30 and the first transparent layer 40 . In another light emitting device 212 according to this embodiment as illustrated in FIG. 11B , the semiconductor light emitting element 10 is mounted on the mounting member 20 such that the p-side electrode 107 and the n-side electrode 108 of the semiconductor light emitting element 10 oppose the mounting member 20 . In other words, the first major surface 10 a on the p-type semiconductor layer (the p-type contact layer 105 ) side of the semiconductor light emitting element 10 opposes the mounting member 20 . The p-side electrode 107 of the semiconductor light emitting element 10 is electrically connected to the p-side substrate electrode 107 e of the mounting member 20 by a p-side bump 107 b ; and the n-side electrode 108 of the semiconductor light emitting element 10 is electrically connected to the n-side substrate electrode 108 e of the mounting member 20 by an n-side bump 108 b . In the case where, for example, a transparent electrode is used as the n-side electrode 108 , a structure may be used in which the n-side electrode 108 contacts the first transparent layer 40 . In another light emitting device 213 according to this embodiment as illustrated in FIG. 11C , the substrate 90 (and the buffer layer 101 ) of the semiconductor light emitting element 10 are removed and the semiconductor light emitting element 10 is mounted on the mounting member 20 such that the p-side electrode 107 and the n-side electrode 108 of the semiconductor light emitting element 10 oppose the mounting member 20 . In the case where, for example, a transparent electrode is used as the n-side electrode 108 , a structure may be used in which the n-side electrode 108 contacts the first transparent layer 40 . As in the light emitting devices 212 and 213 , the efficiency increases similarly to the descriptions recited above even in the case where the semiconductor light emitting element 10 is mounted on the mounting member 20 in a flip chip structure. FIG. 12A , FIG. 12B , and FIG. 12C are schematic cross-sectional views illustrating the configurations of other light emitting devices according to the third embodiment of the invention. In light emitting devices 214 , 215 , and 216 according to this embodiment as illustrated in FIG. 12A , FIG. 12B , and FIG. 12C , the second wavelength conversion layer 80 and the second transparent layer 60 described in regard to FIG. 6 are further provided in the light emitting devices 211 , 212 , and 213 , respectively. Thus, by further providing the second wavelength conversion layer 80 and the second transparent layer 60 , high efficiencies similar to those described in regard to FIG. 6 are obtained. By providing multiple wavelength conversion layers (the first wavelength conversion layer 30 and the second wavelength conversion layer 80 ), the wavelength characteristics of the light emitted by the light emitting device 220 can be controlled easily; and the desired light emission having high color rendition can be realized more easily. An advantage is provided in the light emitting devices 215 and 216 employing the flip chip structure in that the reliability of the light emitting devices can be increased because the wires (the p-side interconnect 107 w and the n-side interconnect 108 w ) are unnecessary and breakage defects, etc., of the wires occurring due to stress in the second transparent layer 60 , etc., do not occur. FIG. 13A and FIG. 13B are schematic cross-sectional views illustrating the configurations of other light emitting devices according to the third embodiment of the invention. In a light emitting device 217 according to this embodiment as illustrated in FIG. 13A , the substrate 90 (and the buffer layer 101 ) of the semiconductor light emitting element 10 are removed; and the n-side electrode 108 is provided on the second major surface 10 b on the n-type semiconductor layer (the n-type contact layer 102 ) side of the semiconductor light emitting element 10 . A transparent electrode, for example, may be used as the n-side electrode 108 . The p-side electrode 107 is provided on the first major surface 10 a on the p-type semiconductor layer (the p-type contact layer 105 ) side. The n-side electrode 108 of the semiconductor light emitting element 10 is electrically connected to the n-side substrate electrode 108 e of the mounting member 20 by the n-side bump 108 b ; and the p-side electrode 107 of the semiconductor light emitting element 10 is electrically connected to the p-side substrate electrode 107 e of the mounting member 20 by the p-side interconnect 107 w. The first transparent layer 40 is provided on the second major surface 10 b side of the semiconductor light emitting element 10 ; and the first wavelength conversion layer 30 is provided between the first transparent layer 40 and the mounting member 20 . In the light emitting device 217 having such a configuration as well, the efficiency is increased by providing the first wavelength conversion layer 30 and the first transparent layer 40 . In another light emitting device 218 according to this embodiment as illustrated in FIG. 13B , the second wavelength conversion layer 80 and the second transparent layer 60 described in regard to FIG. 6 are further provided in the light emitting device 217 . Thus, by further providing the second wavelength conversion layer 80 and the second transparent layer 60 , high efficiency similar to that described in regard to FIG. 6 is obtained. By providing multiple wavelength conversion layers (the first wavelength conversion layer 30 and the second wavelength conversion layer 80 ), the wavelength characteristics of the light emitted by the light emitting devices can be controlled easily; and the desired light emission having high color rendition can be realized more easily. FIG. 14A and FIG. 14B are schematic cross-sectional views illustrating the configurations of other light emitting devices according to the third embodiment of the invention. In a light emitting device 217 a according to this embodiment as illustrated in FIG. 14A , the substrate 90 of the semiconductor light emitting element 10 is electrically conductive; the substrate 90 contacts the first transparent layer 40 ; and the first wavelength conversion layer 30 is provided between the first transparent layer 40 and the mounting member 20 . For example, a SiC substrate is used as the substrate 90 . The n-side electrode 108 is provided on the second major surface 10 b on the substrate 90 side. In such a case, a transparent electrode may be used as the n-side electrode 108 . The p-side electrode 107 is provided on the first major surface 10 a on the p-type semiconductor layer (the p-type contact layer 105 ) side. The n-side electrode 108 of the semiconductor light emitting element 10 is electrically connected to the n-side substrate electrode 108 e of the mounting member 20 by the n-side bump 108 b ; and the p-side electrode 107 of the semiconductor light emitting element 10 is electrically connected to the p-side substrate electrode 107 e of the mounting member 20 by the p-side interconnect 107 w. The first transparent layer 40 is provided on the second major surface 10 b side of the semiconductor light emitting element 10 ; and the first wavelength conversion layer 30 is provided between the first transparent layer 40 and the mounting member 20 . In the light emitting device 217 a having such a configuration as well, the efficiency is increased by providing the first wavelength conversion layer 30 and the first transparent layer 40 . In another light emitting device 218 a according to this embodiment as illustrated in FIG. 14B , the second wavelength conversion layer 80 and the second transparent layer 60 described in regard to FIG. 6 are further provided in the light emitting device 217 a . Thus, by further providing the second wavelength conversion layer 80 and the second transparent layer 60 , high efficiency similar to that described in regard to FIG. 6 is obtained. By providing multiple wavelength conversion layers (the first wavelength conversion layer 30 and the second wavelength conversion layer 80 ), the wavelength characteristics of the light emitted by the light emitting devices can be controlled easily; and the desired light emission having high color rendition can be realized more easily. Thus, in the light emitting device according to the invention, the loss due to returning light reflected by the mounting member 20 being reabsorbed by the light emitting layer 103 of the semiconductor light emitting element 10 can be suppressed by using the first wavelength conversion layer 30 provided on the lower face of the semiconductor light emitting element 10 to perform a wavelength conversion of the first light emitted from the semiconductor light emitting element 10 to the mounting member 20 side and produce the second light L 2 having a wavelength longer than the light emission wavelength (the wavelength of the first light L 1 ) of the semiconductor light emitting element 10 . By providing the first transparent layer 40 between the semiconductor light emitting element 10 and the first wavelength conversion layer 30 , the light (the first light L 1 and the second light L 2 ) reflected by the mounting member 20 can be emitted directly to the outside without passing through the semiconductor light emitting element 10 . Therefore, the light extraction efficiency is increased; and a light emitting device having high efficiency can be provided.
