Abstract:
1. A liquid crystal display device comprising: a TFT substrate on which electrodes for driving liquid crystal are formed; a counter substrate on which color filters are formed; and liquid crystal which is sandwiched between the TFT substrate and the counter substrate, wherein first planar electrodes, an insulation film which covers the first electrodes, and second electrodes which are formed on the insulation film and have a laterally-extending trapezoidal profile including a comb-teeth shaped electrode are formed on the TFT substrate, the liquid crystal is driven by an electric field generated based on potential difference between the first electrode and the second electrode, the second electrodes are arranged by alternately reversing the direction of the trapezoidal shape in the longitudinal direction, and the second electrodes are arranged by alternately reversing the direction of the trapezoidal shape in the lateral direction, the direction of the comb-teeth-shaped electrode is inclined in a specified direction on an upper portion of the trapezoidal shape and is inclined in the direction opposite to the specified direction on a lower portion of the trapezoidal shape, an alignment axis of the liquid crystal on the TFT substrate is arranged equal to the lateral direction, the color filters are formed on the counter substrate in a stripe shape in the longitudinal direction, and first light blocking films are formed on boundary portions of the color filter on the counter substrate in a stripe shape in the longitudinal direction.
