Abstract
The object is to provide a liquid crystal display reducing degradation in image quality. A liquid crystal display apparatus comprises a first planar electrode, a first insulator layered over an upper surface of the first planar electrode, a planar pixel electrode layered over an upper surface of the first insulator, a second insulator layered over an upper surface of the pixel electrode, a second planar electrode that covers the pixel electrode and that is layered over an upper surface of the second insulator, and a liquid crystal layer disposed over an upper surface of the second planar electrode. The second planar electrode includes an aperture portion including a first region and a second region integrated with a first region, the first region is a region is overlapped with both the first planar electrode and the pixel electrode, the second region is overlapped with the first planar electrode and is not overlapped with the pixel electrode, and a first angle between a first side of the first region and a first virtual line dividing the aperture portion into the first region and the second region is equal to or smaller than 90 degrees.
