  • Patent number: 11119374
    Abstract: According to one embodiment, a display device includes a liquid crystal layer between a first substrate and a second substrate. The first substrate includes a wiring line and a pixel electrode. The liquid crystal layer contains a stripe-shaped polymer extending in a first direction and a liquid crystal molecule. The liquid crystal layer contains a first polymer in an area overlapping the wiring line and a second polymer in an area overlapping the pixel electrode. The first polymer includes a first portion extending in a direction different from the first direction. The second polymer includes a second portion extending in a direction different from the first direction. A density of the first portion is higher than a density of the second portion.
