Abstract: 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.

Abstract: To take measures against the phenomenon of difficulty for the orientation film material to flow into the through-hole when the diameter of through-holes which connects the pixel electrode and the source electrode becomes small.An interlayer insulating film 109 made of SiN is formed on a counter electrode, and a pixel electrode 110 having a slit 1101 is formed on the interlayer insulating film 109. A through-hole 111 which connects the pixel electrode 110 and the source electrode of a TFT has a large opening on the upper side, a small opening on the lower side, and an inner wall extending between the large opening and the small opening. The pixel electrode 110 covers the through-hole 111 on an inner side of the pixel of the through-hole 111 but does not cover a periphery of the large opening of the through-hole on an outer side of the through-hole 111. Consequently, an orientation film material can easily flow from a starting point given by an end portion of the pixel electrode into the inside of the through-hole.

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.

Abstract: A TFT substrate and a counter substrate are bonded via a seal material. Alignment films are applied to entire surfaces of the TFT substrate and the counter substrate so as to realize even thickness of the alignment film. This allows a display region to be formed up to the area around the seal material. The alignment film is photo-alignment processed. An organic film formed of the material which is not photo-aligned is interposed between the alignment film and the seal material. High bonding strength between the organic film and the seal material improves reliability of a seal portion as well as reduces a frame region.
