ABSTRACT:
An IPS-mode LCD device includes a TFT substrate and a counter substrate sandwiching therebetween a LC layer. Each pixel includes a pixel electrode covered by a passivation film formed on the TFT substrate, and a common electrode formed on the top surface of the passivation film. The passivation film has a first thickness at a portion in contact with the common electrode and a second thickness smaller than the first thickness at a portion in contact with the pixel electrode, thereby having a flat top surface of the passivation film.
