Liquid crystal display device

A liquid crystal display device having a first substrate and a second substrate which are arranged to face each other with liquid crystal sandwiched therebetween, wherein

• the first substrate forms a plurality of gate signal lines and a plurality of drain signal lines on a liquid-crystal-side surface thereof,
• assuming a region surrounded by a pair of neighboring gate signal lines and a pair of neighboring drain signal lines as a pixel region of one pixel,
• the pixel includes a thin film transistor which is turned on in response to a signal from the gate signal line, a pixel electrode to which a signal from the drain signal line is supplied via the thin film transistor, and a counter electrode which generates an electric field for driving the liquid crystal between the pixel electrode and the counter electrode which are formed on the liquid-crystal-side surface of the first substrate,
• the counter electrode is formed of a transparent conductive film having a planar shape which is formed in a state that the transparent conductive film of the counter electrode extends over the neighboring pixel striding over at least the gate signal line, the transparent conductive film of the counter electrode being formed on a first insulation film which is formed on the first substrate so as to cover the gate signal line,
• the pixel electrode is formed of a transparent conductive film which includes a plurality of linear portions arranged parallel to each other and a frame portion which connects end portions of the linear portions to each other, the transparent conductive film of the pixel electrode being formed in each pixel region on a second insulation film which is formed on the first substrate so as to cover the counter electrode, and the plurality of linear portions of the pixel electrode being arranged on the counter electrode in an overlapping manner, and
• a gate-signal-line-side frame portion of the pixel electrode is formed on the pixel side of the gate signal line in an overlapping manner.
