BACK LIGHT MODULE AND DISPLAY DEVICE

摘要

Provided are a back light module and a display device. The back light module comprises: a light source (10); a back panel (11); a light-guiding plate (12); and positioning members (13). The back panel (11) has a frame for accommodating the light-guiding plate (12). The light source (10) is disposed at an inner side of a side plate (113) of the back panel (11) and arranged opposite to a light-entering surface of the light-guiding plate (12). The positioning members (13) are disposed at two ends of the side plate of the back panel (11) where the light source (10) is disposed and positioned between the light-entering surface of the light-guiding plate (12) and the light source (10). The back light module ensures a constant distance between the light-entering surface of the light-guiding plate (12) and the light source (10), thereby increasing uniformity of an image displayed on a display device. Therefore, a distance between the light-entering surface of the light-guiding plate (12) and a light-exiting surface of the light source (10) is not among factors affecting quality of the image displayed on the display device.
