Abstract

A multi-domain alignment liquid crystal display device in which liquid crystal molecules are aligned through a simple process and panel gap is maintained in stable fashion includes a first plate having a thin-film transistor provided at each point of intersection of a scanning line and signal line, a pixel electrode connected to the thin-film transistor and a first orientation layer formed on the pixel electrode and defining a curved surface, and a second plate having RGB color layers, an counterelectrode provided so as to oppose the pixel electrode, and a second orientation layer. A columnar spacer for regulating the panel gap is provided between the two opposing plates, and liquid crystal is sandwiched between the two plates and subjected to multi-domain alignment by the first orientation layer having the curved surface and the columnar spacer.
