Abstract: A display device includes a backlight module and a display panel. The backlight module includes a light guide plate, a light source, a reflecting sheet and a light transmissible member. The light source is disposed at a first side of the light guide plate and used for emitting a light into the light guide plate, wherein the light has a first color. The reflecting sheet is disposed at a second side of the light guide plate. The light transmissible member is disposed between the light guide plate and the reflecting sheet and has a second color, wherein the first color and the second color are complementary colors, such that white light is generated when the light guided by the light guide plate passes through the light transmissible member. The display panel is disposed above the light guide plate.

Abstract: A structure for eliminating bright lines of a tiled backlight module is provided. The structure includes a light guide plate, and a plurality of light sources. The light guide plate includes a plurality of rows of optical elements. The rows of optical elements extend in parallel. The light sources are provided at least one side of the light guide plate for projecting a light into the light guide plate and generating a regular but non-uniform light outputting performance of the light guide plate. Therefore, a brightness of areas where the optical elements are located is higher than the rest areas, so that the light guide plate achieves a regular but non-uniform light emitting performance. Accordingly, the bright lines occurred at joints between two light guide plates are enshrouded by the high brightness areas, and become hard to identify or even undistinguishable, thus “eliminated”.
