Abstract
A liquid crystal display device with a pair of substrates which are arranged to face each other with liquid crystal therebetween, columnar spacers having the substantially equal height formed on a liquid-crystal-side surface of one substrate, and the columnar spacers include the columnar spacer which is contact with a liquid-crystal-side surface of another substrate and the columnar spacer which is not contact with the liquid-crystal-side surface of another substrate.
Claims5
A liquid crystal display device comprising:
- a first substrate and a second substrate with a liquid crystal layer therebetween;
- a plurality of gate signal lines and a plurality of drain signal lines, the gate signal lines and the drain signal lines being formed on the second substrate,
- a plurality of pixel regions defined by the gate signal lines and the drain signal lines,
- a plurality of counter voltage signal lines are arranged in parallel with the gate signal lines,
- a plurality of spacers formed on the first substrate, the respective spacers being arranged in a position which counters the respective gate signal lines defining a corresponding pixel region,
- a plurality of projection portions formed on the second substrate, the respective projection portions being arranged on the gate signal line defining a corresponding pixel region, each projection portion formed by at least a semiconductor layer and a conductive layer, the conductive layer being formed over the semiconductor layer,
- wherein the plurality of spacers include at least one of first spacer and at least one of second spacer, a region of the at least one of the first spacer formed corresponds to a region of the respective projection portions formed in a plane view, and a region of the at least one of the second spacer formed does not correspond the region of the respective projection portions formed in a plane view.
