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 filmmade of SiN is formed on a counter electrode, and a pixel electrodehaving a slitis formed on the interlayer insulating film. A through-holewhich connects the pixel electrodeand 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 electrodecovers the through-holeon an inner side of the pixel of the through-holebut does not cover a periphery of the large opening of the through-hole on an outer side of the through-hole. 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.
