发明名称 液晶表示装置
摘要 In a liquid crystal display device using a cylindrical spacer to define the gap between a TFT substrate and a counter substrate, the TFT substrate does not include an organic passivation film, in which the cylindrical spacer is formed on an inorganic passivation film. An overcoat film is formed to cover a black matrix and color filters in the counter substrate. A concavo-convex mount is formed in the overcoat film. The top of the cylindrical spacer is brought into contact with the concavo-convex mount. The oriented film is not attached to the top of the cylindrical spacer and the convex portion of the concavo-convex mount. Thus, even if horizontal displacement occurs in the TFT substrate or the counter substrate, it is possible to prevent the occurrence of bright spots due to the scraping of the oriented film caused by the friction between the TFT substrate and the counter substrate.
