摘要： In a liquid crystal display device, a common electrode is formed on an organic passivation film, an interlayer insulating film is formed on the common electrode, a pixel electrode with a slit is formed on the interlayer insulating film, and a through hole is formed in the organic passivation film and the interlayer insulating film, so that the pixel electrode is connected to a source electrode of a TFT through the through hole. Further, the taper angle around the upper base of the through hole is smaller than the taper angle around the lower base. Thus, the alignment film material can easily flow into the through hole when the diameter of the through hole is reduced to connect the pixel and source electrodes, preventing display defects such as uneven brightness due to the absence of the alignment film or due to the alignment film irregularity around the through hole.

摘要： 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.
