Patent ID: 8724072

Claim:
A liquid crystal device, comprising: a first substrate and a second substrate which are arranged to face each other with a liquid crystal layer there between; a plurality of gate signal lines and a plurality of drain signal lines formed on the first substrate; a plurality of pixel regions defined by the drain signal lines and the gate signal lines; at least a thin film transistor formed on the first substrate in each pixel region, each thin film transistor having a first semiconductor layer; a plurality of column spaces formed on the second substrate including first columnar spacers and second columnar spaces, the columnar spacers being formed on all of the gate signal lines in plain view; and a second semiconductor layer formed on the gate signal lines, and wherein the first columnar spacers contact to the first substrate side of the second substrate and the second columnar spacers do not contact to the first substrate side of the second substrate, the first columnar spacers and the second columnar spacers are arranged on the gate signal lines, the first columnar spacers are arranged in a formation region of the second semiconductor layers, and the second columnar spacers are arranged in a non-formation region of the second semiconductor layers.
