Abstract
The present invention provides a liquid crystal display panel which has a via hole region and a display region. The liquid crystal display panel includes a backlight film layer. The backlight film layer includes a reflective plate and a light guiding plate arranged in sequence. In the via hole region, a black light-shielding adhesive is attached to the reflective plate. The reflective plate includes a first reflective sheet and a second reflective sheet which is bent upward. The second reflective sheet fixes the backlight film layer by the upward bending of the second reflective sheet. The black light-shielding adhesive includes a first black light-shielding adhesive portion and a second black light-shielding adhesive portion which is bent upward. The second black light-shielding adhesive portion is bent upward to form a black wall to cover the light guiding plate.
