Abstract
In a TFT substrate partially constituting a liquid crystal panel, gate bus lines and data bus lines are provided in orthogonal directions to each other, and a switching element (TFT) is provided in the vicinity of each of intersecting points of these bus lines. Further, Cs bus lines forming auxiliary capacitances (Cs) together with picture element electrodes each of which is provided for each picture element are provided in the direction parallel to the data bus lines. The gate bus lines, the data bus lines, and the Cs bus lines are provided at equal wiring intervals, respectively, and picture element regions each having the shape of a square are delimited by the Cs bus lines as boundaries.
Claims12
A liquid crystal panel comprising:
- a plurality of gate bus lines extending in a first direction;
- a plurality of data bus lines extending in a second direction intersecting the first direction;
- a switching element provided for each picture element, the switching element using part of a corresponding gate bus line as a gate electrode and being electrically connected to a corresponding data bus line;
- a picture element electrode provided for each picture element and electrically connected to a corresponding switching element;
- a counter electrode placed with liquid crystals interposed between the counter electrode and the picture element electrode;
- and
- a plurality of auxiliary capacitance bus lines extending in the second direction and each forming an auxiliary capacitance together with the picture element electrode for each picture element,
- wherein a picture element region having the shape of a square is delimited by the respective auxiliary capacitance bus lines as boundaries.
