LIGHT GUIDE PLATE AND MANUFACTURING METHOD THEREFOR, BACKLIGHT MODULE AND DISPLAY DEVICE

摘要

A light guide plate, a method for manufacturing the light guide plate, a backlight module provided with the light guide plate, and a display device equipped with the backlight module. The light guide plate comprises a light guide layer (1) and a reflecting layer (2). A lower surface (11) of the light guide layer (1) is a light-reflecting surface. An upper surface of the light guide layer (1) is a stepped surface, which comprises an upper step surface (12), a lower step surface (14), and an inclined surface (13) connected between the upper step surface (12) and the lower step surface (14). The lower step surface (14) is an out-light surface. The reflecting layer (2) covers the inclined surface (13).
