  • Patent number: 10802316
    Abstract: The present invention provides a liquid crystal display device which can prevent a camera image from being adversely affected by the birefringence of external polarized light which enters a camera through the liquid crystal layer. In a liquid crystal display device (1A), light to enter a camera (3) passes through a part of a liquid crystal panel (10A). The liquid crystal panel (10A) is configured so that the first part of the liquid crystal layer (14), which first part is located in the camera light transmissive region (S1) allowing the light to enter the camera 3 to pass therethrough, has a retardation R1 represented by the following formula: R1=m? (where (i) m is a positive integer and (ii) ? is a wavelength of the light passing through the liquid crystal layer).

  • Publication number: 20200236259
    Abstract: Disposing a functional device such as a camera on a display surface widens a frame. A display device (2) includes a display panel (DP) including a first substrate (5). The display panel has a transparent section (TS) from which display light does not go out and which has a partial region (5s) of the first substrate. In plan view, the transparent section which is larger than a pixel (PX) is disposed on an inner side of an edge of a display area (3) or is disposed to cut out the display area. The display panel has a back surface on which a functional device (FD) configured to perform at least one of light reception or light emission is disposed to overlap the transparent section.
