Abstract

The invention provides a display device. The display device comprises a display panel and a backlight module, the backlight module is used for providing a backlight source for the display panel, and the backlight module comprises a light source; the light source is located on the side of the light guide plate, and the light guide plate is used for converting light emitted by the light source intoan area source; the diffusion plate is used for homogenizing the light emitted by the light guide plate. Via the display device disclosed in the invention, the display effect is excellent even for thedisplay panel with an extremely narrow BM area.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] With the development of modern industry and the increasingly fierce competition in the semiconductor industry, the market for display devices with liquid crystal display panels is rapidly expanding. [0003] Currently, a display device using a liquid crystal display panel also includes a backlight module for providing a backlight source for the display panel. The display panel includes a display area and a black border area (Black Matrix, BM) surrounding the display area. The backlight module usually includes structural components protruding into the display area of ​​the display panel when viewed from above, and the protruding parts of these structural components into the display area will cause defects such as dark shadows in the display area. Usually, in order not to affect the normal display of the display panel, thes...
