Abstract
A display device includes a backlight module positioning adhesive structure and a liquid crystal panel that includes a bezel zone and a light transmitting zone. A backlight module includes a reflector plate, a light guide plate, and the optic film that are sequentially stacked on each other and surrounded by a mold frame. The backlight module further includes a double-sided adhesive tape that includes first and second layers stacked on each other. The second layer includes a light shielding section and a light transmitting section connected to the light shielding section. The double-sided adhesive tape is adhesively bonded between the bezel zone of the liquid crystal panel and the backlight module. The light shielding section is located on an edge portion of the optic film and the mold frame. The light transmitting section extends towards the light transmitting section of the optic film.
