Abstract
A display device comprises: a backlight unit; a liquid crystal panel comprising a lower polarizer, an upper polarizer, and a first substrate and a second substrate; and a cover plate on the liquid crystal panel, wherein a camera hole passes through the backlight unit and up to the lower polarizer, an interference prevention hole is located at a position corresponding to the camera hole, and the camera hole is not in the first substrate and the second substrate. The display device has a hole with a uniform size, decreased processing cost, increased structural rigidity, and does not have thermal deformation, can prevent defects such as generation of air bubbles, bending deformation, and distortion of a light path due to the hole and the vacuum bonding while increasing the visible light transmittance and resolution of the camera, and improving the appearance quality of the display device.
