Abstract:
1. A liquid crystal display cell comprising: a substrate; an insulating layer formed on the substrate; a data line that is formed on the insulating layer and is supplied with a pixel signal; a planarizing layer that covers the data line and the insulating layer and has a groove formed above the data line, the groove having two shoulders, the planarizing layer having a flat surface on at least one of the shoulders of the groove; a common electrode formed on internal walls of the groove and on the flat surface, wherein a portion of the common electrode is located above the data line; a pixel electrode formed on the planarizing layer; a scan line supplied with a scan signal; a switching element that controls a voltage of the pixel electrode based on the scan signal and the pixel signal; and a liquid crystal layer disposed on the planarizing layer.
