  • Patent number: 11036106
    Abstract: A decline in the display quality in portion areas corresponding to source lines that run through an inner non-display area in a display area is reduced. The arrangement of source lines that run through an inner non-display area is changed in an upper change area and a lower change area so that the source lines that are simultaneously driven are not adjacent to each other in a display area and are adjacent to each other in a passage area.

  • 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.

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).
