液晶表示装置
Document Type and Number:
Japanese Patent JP4600547
Kind Code:
B2
Abstract:
The present invention provides a liquid crystal display device realizing improved reliability by preventing occurrence of a pixel defect. A liquid crystal display includes first and second substrates. A spacer maintains a distance between the first and second glass substrates. A liquid crystal layer is provided between the first and second substrates. A pixel electrode film and a common electrode film are formed over a base insulation film of the first substrate so as to sandwich a pixel insulation film in between. The common electrode film, the pixel electrode film or both of them are partly removed in a region corresponding to the spacer, and the pixel insulation film is partly removed in that region. It prevents the film structure from being broken due to deformation of the base insulation film made of a soft material caused by a pressure applied onto the spacer.
