## Abstract

A liquid crystal display apparatus includes scan lines, data lines perpendicular to the scan lines, a first pixel, a second pixel adjacent to the first pixel, and a black matrix layer. The first pixel includes a first main pixel and a first sub pixel. The first main pixel and the first sub pixel are arranged along a direction of the scan line. The second pixel includes a second main pixel and a second sub pixel. The second main pixel and the second sub pixel are arranged along the direction of the scan line. The black matrix layer covers the first pixel and the second pixel. The black matrix layer covers portions of the first main pixel, the first sub pixel, the second main pixel, and the second sub pixel. The first pixel and the second pixel are arranged along a direction of the data line.
