Abstract
The invention provides a liquid crystal display device which is highly reliable even with a slim frame area. Ina liquid crystal display device having a display area and a frame area, the frame area includes, in an area close to the display area, a flat portion where an organic insulation film, a transparent conductive film, and an alignment film are stacked in this order and, in an area away from the display area, a groove structure formed in the organic insulation film, the groove structure being continuous surrounding the display area. The organic insulation film is less wettable than the transparent conductive film by the alignment film ink.
