Description

Display device

The present invention relates to a display device.

Since the liquid crystal display device (LCD Display) is thin in thickness, light in weight, and easy to carry, it has the advantage of low radiation compared to the CRT display, so that the demand in recent years has rapidly increased. Among them, the design of the narrow bezel is especially welcome.

Figure 1 is a schematic view of a conventional liquid crystal display device. As shown in FIG. 1, the display device includes a display module 10, a rear case 50, and a front case 70. The display module 10 has a display surface 11 and a back surface 13. The rear housing 50 is located on the outer side of the back panel 13 of the display module 10, and includes a rear housing 52 and a rear housing wall 54. The rear housing wall 54 surrounds the rear housing 52 and is displayed. The face 11 extends to the side of the display module 10. The front case 70 has a front case frame 72 and a front case wall 74. The front housing frame 52 partially covers the display surface 11, and the front housing wall 74 surrounds the front housing frame 72 and extends toward the rear surface 13 to the outside of the rear housing wall 54.

As shown in FIG. 1, the display module 10, the rear case 50, and the front case 70 are generally locked and fixed by using a screw 20. Further, the screw 20 passes through the front shell wall 74 and the rear shell wall 54 and is locked to the side of the display module 10, thereby limiting the display module 10, the rear shell 50 and the front shell 70 on the display surface 11 The displacement in the normal direction. However, this design is disadvantageous for the reduction of the width of the frame because the front case wall 74 and the rear case wall 52 are located on the side of the display module 10.
