Abstract:
A liquid crystal display device comprising:a pair of substrates at least one of which is transparent and between which a liquid crystal layer is interposed; a plurality of gate lines and a plurality of drain lines being formed on an inner surface of one of the pair of substrates; a thin film transistor being disposed at an intersecting portion of one of the plurality of gate lines and one of the plurality of drain lines; a pixel electrode being connected to the thin film transistor; a counter electrode being disposed opposite to the pixel electrode; wherein each of the gate lines has a dimension in a direction of an extension direction of the drain lines which is substantially constant between adjacent drain lines; an edge portion of a semiconductor layer situated under a source electrode of the thin film transistor is arranged within an edge of the gate line situated under the semiconductor; and the semiconductor layer has a first portion and a second portion, a dimension of the first portion in the extension direction of the drain lines being narrower than a dimension of the second portion in the extension direction of the drain lines.
