Abstract:
A lighting device includes a light source array, a wavelength converting member, and a light guide plate. The light source array includes light sources configured to emit primary light rays. The wavelength converting member includes a wavelength converting portion, a holding portion, and non-wavelength converting portions. The wavelength converting portion contains phosphors configured to emit secondary light rays when excited by the primary light rays. The wavelength converting member is disposed between the light guide plate and the light source array. The light guide plate includes a light entering surface, a light exiting surface, an opposite surface that is on an opposite side from the light exiting surface, and a light reflecting and scattering pattern. The light reflecting and scattering pattern includes complementary color dots formed in sections of the opposite surface on non-wavelength converting portion sides. The complementary color dots absorb the primary light rays.

Claim (Index 5):
A lighting device comprising:\n a light source array comprising a plurality of light sources configured to emit primary light rays in a predefined wavelength range and arranged in line; and at least one wavelength converting member disposed along a length direction of the light source array to be opposed to the light source array, the at least one wavelength converting member comprising:\n a wavelength converting portion containing phosphors configured to secondary light rays in a wavelength range different from the wavelength range when excited by the blue light rays; \n a holding portion holding the wavelength converting portion to surround the wavelength converting portion and having light transmissivity and an elongated shape; and \n a non-wavelength converting portion formed at an end of the holding portion with respect to a longitudinal direction of the holding portion and configured to pass the primary light rays emitted by the light sources; and \n a light guide plate, wherein the at least one wavelength converting member is disposed between the light guide plate and the light source array, the light guide plate comprises:\n a light entering surface through which light rays enter, the light rays including the primary light rays and the secondary light rays converted from the primary light rays emitted by the light sources and traveling through the at least one wavelength converting member from a light source side to a light guide plate side; \n a light exiting surface through which the light rays exit; and \n an opposite surface disposed on an opposite side from the light exiting surface, and \n the lighting device further comprises:\n a reflection member disposed to cover the opposite surface and configured to reflect light rays; and \n a complementary color member configured to exhibit a complementary color of a reference color exhibited by the primary light rays and disposed between the opposite surface and the reflection member to overlap a section of the opposite surface extending from the non-wavelength converting portion in a light emitting direction of the light sources.
