Liquid crystal display device

A liquid crystal display device comprising:

• pixels arranged in a matrix in a display region above a substrate;
• a thin film layer for laser writing formed in a non-display region excluding the display region;
• and
• a transparent insulating film extending from the display region to the non-display region and formed on the thin film layer, wherein
• the transparent insulating film includes at least
• an organic insulating film which is formed of an organic compound for planarizing a surface of the substrate, and
• an inorganic insulating film which is formed of an inorganic compound and formed on the organic insulating film, and
• a groove portion extending from the inorganic insulating film to the organic insulating film is formed so as to annularly surround the periphery of the forming region of the thin film layer.

• a transparent electrode film which is formed in the opening of the inorganic insulating film to cover the organic insulating film exposed from the opening of the inorganic insulating film,
• a groove portion extending from the inorganic insulating film to the organic insulating film is formed so as to annularly surround the periphery of the forming region of the thin film layer, and
• the groove portion is covered with the transparent electrode film.
