Patent ID: 8664660

Claim:
A liquid crystal display device comprising; a first pixel over a first substrate, and comprising: a first TFT comprising: a first portion of a first semiconductor layer; a first gate insulating film over the first portion of the firsts semiconductor layer; and a first gate electrode over the first gate insulting film, a capacitor comprising: a first layer comprising a second portion of the first semiconductor layer; a second layer over the first layer, and comprising a same layer as the first gate insulating film; and a third layer over the second layer, and comprising a same layer as the first gate electrode, wherein a third portion of the first semiconductor layer extends to a second pixel next to the first pixel, the third portion of the first semiconductor layer being contiguous with the first portion of the first semiconductor layer, a first insulating film comprising silicon nitride, and over and in contact with the first gate electrode and the first gate insulating film; a second insulating film comprising an organic insulating, material, and over the first insulating film; a pixel electrode over the second insulating film; a first columnar spacer and a second columnar spacer over the pixel electrode; transparent conductor film over the first columnar spacer and the second the second columnar spacer; a shielding film over the transparent conductive film; and a second substrate over the shielding film, wherein a size of the first columnar spacer is different cut from a size of the second columnar spacer.
