Problems solved by technology

[0002] The liquid crystal display device mainly includes a display panel and a backlight. The backlight includes a light source, a light guide plate and an optical film. On one side of the light source, part of the light from the light source will directly shine on the optical film. In order to prevent the light directly irradiated on the optical film from entering the display panel, a light-shielding glue will be attached to the optical film to prevent the direct light from entering the display panel. The light on the optical film is blocked, but the process precision of the light-shielding adhesive is high, and a slight error will cause the light emitted by the light source to pass through the optical film and irradiate the display panel directly, which in turn will cause the brightness of the display device to appear. The problem of poor optical quality due to unevenness makes the display effect of the display device unsatisfactory
