     BACKGROUND OF THE INVENTION 
     Field of the Invention 
       [0002]    The present invention relates to an enclosure, and especially to an enclosure used in liquid crystal display device. The enclosure is configured with a bezel frame and a base frame, and at least a pair of resilient prongs configuring a resilient dovetail-shaped tab in the bezel frame to snugly and efficiently inter-engage with a corresponding dovetail-shaped retaining gap defined in an edge of a substrate. 
       Related Arts 
       [0003]    With the growing competition of the liquid crystal display devices, it is more and more important to come out with differentiated designs. For instance, super thin and narrowed frame is one of the trends in design liquid crystal display device. 
         [0004]    As shown in  FIG. 1 , the super thin/narrow frame LCD  10  includes a front frame  1 , a liquid crystal panel  2 , a plurality of optical components  4 , and a base frame  5 . The front frame  1  includes a bezel  6  for pressing the liquid crystal panel  2  via buffering components so as to shield an end portion  7  of the liquid crystal panel and to position the liquid crystal panel  2  therein. The front frame  1  further includes a lateral wall  8  perpendicular to the bezel  6 . The front frame  1  is attached to the lateral wall  8  through screws or equivalents. 
         [0005]    As the above-mentioned trend, the bezel  6  may increase the thickness (H) of the liquid crystal panel  2 , while the lateral wall  8  may increase the thickness (D), which is detriment to the super thin and narrowed design.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0019]    Embodiments of the invention will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown. 
         [0020]    Referring to  FIG. 2 , a partial cross sectional view of the LCD made in accordance with a first embodiment of the present invention is shown. The liquid crystal display device  100  includes a liquid display panel module  20 , a bezel fame  30 , a base frame  40 , and an optical component  50 . The bezel frame  30  and the base frame  40  jointly configure into an enclosure to house the liquid display panel module  20  and the optical components  50 . 
         [0021]    The bezel frame  30  is configured with a lateral wall  31 , a bezel  32 , a supporting platform  33 , and a mounting portion  34 . The bezel  32  extends from a top end of the lateral wall  31 . In this embodiment, the supporting platform  32  extends also from the lateral wall  31  and jointly define a retaining gap  35  with the bezel  32 . The bezel  32  is preferably formed with a lead-in surface  321 . The mounting portion extends downward from the supporting platform  32 . The mounting portion  34  is in parallel with respect to the lateral wall  31  such that a retaining trough  36  is defined therebetween. 
         [0022]    The liquid crystal display panel module  20  includes a thin-film transistor (TFT) substrate  22  and a color filter (CF) substrate  21  mounted on top of the TFT substrate  22  which is larger than the CF substrate  21  in dimension. A lead-in edge  23  is spared in the liquid crystal display panel module  20  and which can be readily inserted into the retaining gap  35  in a way such that a top surface of the liquid crystal display panel module  20  is flushed with a top surface of the bezel  32 . The TFT substrate  22  is defined with a gluing area, and the arrangement of the supporting platform  33 , the lead-in surface  321  of the bezel  32  can be readily used to control the flowing direction of the glue in that gluing area. Specially, the lead-in surface  321  will preferably lead the glue to flow out of the retaining gap  35  and settle in an area between the CF substrate  21  and the lead-in surface  321  of the bezel  32 . 
         [0023]    The base frame  40  includes a bottom wall  41 , a first peripheral wall  42  extending upward from the bottom wall  41 . A mounting space  43  is defined by the bottom wall  41 , the first peripheral wall  42  and the supporting platform  33  for housing the optical components  50  therebetween. The first peripheral wall  42  is properly fitted into the retaining trough  36  defined between the lateral wall  31  and the mounting portion  34  so as to keep all elements in correct and intended positions. It should be noted that the mounting portion  34  can be omitted and replaced by the first peripheral wall  42  and the supporting platform  33 . 
         [0024]    Referring now to  FIG. 3 , along with  FIGS. 7, 8 and 9 , the lead-in edge  23  of the TFT substrate  22  is defined with a plurality of positioning slots  24  jointly defined by a pair of inclined surfaces  241  therein. The positioning slot  24  has a dovetail-shaped configuration, i.e. having a narrow mouth, while a larger pocket therein. 
         [0025]    Referring to  FIG. 4 , again along with  FIGS. 7, 8, 9 and 10 . It should be noted that  FIG. 4  is viewed from a bottom direction, i.e. a direction opposite to the bezel  32 . A plurality of resilient tabs  38  extends from the lateral wall  31  into the retaining gap  35 . An end wall  37  is connected to the end of the lateral wall  31 . The end wall  37 , the bezel  32  and the supporting platform  33  are integrally formed together. 
         [0026]    The resilient tab  38  is configured by a first prong  381  and a second prong  382 . Each of the first and second prongs  381 ,  382  is defined with a lead-in  383 . The first and second prongs  381 ,  382  extend from the lateral wall  31  into the retaining gap  35  so as to meet and engage with the positioning slot  24  of the lead-in edge  23  of the TFT substrate  22 . Every two adjacent resilient tabs  38  jointly a receiving space  384 . The interengagement between the resilient tabs  38  and the positioning slots  24  can be readily appreciated by the disclosure of  FIG. 9 . Since both the resilient tabs  38  and the positioning slots  24  are configured into the dovetail-shaped, as a result, a reliable and compact interengagement therebetween can be ensured and benefited. The arrangement of the lead-in  383  will ensure the engagement smooth and easy. As any skilled in the arts can readily appreciate the convenience of this arrangement, it is believed that no detailed description is needed. 
         [0027]    Referring to  FIG. 5 , a partial cross sectional view of the LCD in accordance with a second embodiment of the present invention is disclosed. 
         [0028]    The liquid crystal display device  200  is substantially similar to the liquid crystal display device  100 . The difference resides the engagement or assembly between the bezel frame  30 ′ and the base frame  40 ′. In this embodiment, the base frame  40 ′ is formed with a second peripheral wall  44  and jointly defining a mounting trough  45  along with the first peripheral wall  42 ′ so as to securely receive the mounting portion  34 ′ of the bezel frame  30 ′. 
         [0029]    It can be readily appreciated from  FIG. 5  as in this embodiment, the lateral wall  31 ′ is also flushed with the first peripheral wall  42 . The lateral wall  31 ′ can be shortened as the mounting portion  34 ′ is snugly positioned within the mounting trough  45 . 
         [0030]    It should be noted that the lateral wall  31 ′, the supporting platform  33 ′ and the mounting portion  34  can be made individually, and then assembled together; or alternatively, they can be integrally formed. 
         [0031]    Referring to  FIG. 6 , a partial cross sectional view of the LCD in accordance with a third embodiment of the present invention is disclosed. 
         [0032]    The liquid crystal display device  300  is substantially similar to the liquid crystal display device  200 . The difference again resides the engagement or assembly between the bezel frame  30 ″ and the base frame  40 ″. 
         [0033]    In this embodiment, the supporting platform  33 ″ is integrally formed with the base frame  40 ″ while extending upward to define the retaining gap  35  (see  FIG. 2  for reference), i.e. the supporting platform  33 ″ is integrally formed with the second peripheral wall  44 ′. In addition, the lateral wall  31 ′ is aligned with the first peripheral wall  42 ″. 
         [0034]    In this embodiment, the base frame  40 ′ is formed with a second peripheral wall  44  and jointly defining a mounting trough  45  along with the first peripheral wall  42 ′ so as to securely receive the mounting portion  34 ′ of the bezel frame  30 ′. Both the lateral wall  31 ″ and the first peripheral wall  41 ″ is defined with mating joints  311  at their mating ends for readily and convenient engagement. 
         [0035]    In this third embodiment, the bottom wall  41 ″, the first peripheral wall  42 ″, the second peripheral wall  44 ″ and the supporting platform  33 ″ can be formed individually, and then assembled together, or they can be integrally formed together. It is noted that the lateral wall  31 ″ of the bezel frame  30 ″ is preferably formed separately. 
         [0036]    From the above descriptions of the preferable embodiments, it can be readily appreciated that with the interengagement between the retaining tabs and the positioning slots between the bezel frame and the TFT substrate, the purpose and goal of the present invention can be properly achieved. Mostly importantly, the top surface of the display panel is flushed with the top surface of the bezel through this effective arrangement. Other benefits can be readily achieved as well. 
         [0037]    It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the invention.
