Abstract

The present disclosure proposes an array substrate, an LCD panel, and an LCD. A plurality of subpixels are arranged in the same pixel zone and share the same via hole so that a common electrode can receive scanning voltage. This structure enhances the aperture ratio of a pixel and the light transmittance of a pixel.
