Abstract: A display device is provided, including a backlight module and a liquid crystal display module. The backlight module is provided with a through hole. The liquid crystal display module includes a display panel and a lower polarizing film and an upper polarizing film arranged on two opposite sides of the display panel. A first via hole is in the lower polarizing film. A second via hole is in the upper polarizing film and arranged corresponding to the first via hole. A light shielding portion is arranged at two side edges of the second via hole. Such configuration avoids light leakage from the first via hole and the second via hole of the liquid crystal display module, and improves shooting performance of the camera module and also enhances market competitiveness.
