Abstract:
The present invention prevents the shaving of an alignment film caused by a columnar spacer in a liquid crystal display device of an IPS method using photo-alignment. A plinth higher than a pixel electrode is formed at a part where a columnar spacer formed over a counter substrate touches a TFT substrate. When an alignment film of a double-layered structure is applied over the pixel electrode and the plinth, the thickness of the alignment film over the plinth reduces by a leveling effect. When photo-alignment is applied in the state, a photodegraded upper alignment film over the plinth disappears and a lower alignment film having a high mechanical strength remains. As a result, it is possible to prevent the shaving of the alignment film.

Claim (Index 1):
A liquid crystal display device comprising:\n a TFT substrate, a counter substrate, a liquid crystal layer between the TFT substrate and the counter substrate, wherein a spacer is formed on the counter substrate to determine a distance between the TFT substrate and the counter substrate, a pixel electrode, a TFT (thin film transistor), and a plinth, which opposes to the spacer, are formed on the TFT substrate, a distance between the TFT substrate and a top of plinth is bigger than a distance between the TFT substrate and a top of the pixel electrode, wherein an alignment film is formed on the plinth and the pixel electrode, a first material and a second material are included in the alignment film, the first material exhibits photo-alignment effect, the alignment film is constituted by an upper layer and a lower layer, the upper layer is adjacent to the liquid crystal layer, a ratio of the first material to the second material is bigger in the upper layer than in the second layer, when the thickness of the lower alignment film is defined as p1 and the thickness of the upper alignment film is defined as p2, p2/p1 over the plinth is smaller than p2/p1 over the pixel electrode.
