Abstract:
1. An active matrix liquid crystal display apparatus in which a plurality of pixels are disposed in a matrix and a voltage applied to liquid crystal is controlled in each of the pixels, the apparatus comprising: a plurality of gate lines extending in the row direction, to which a gate voltage is applied; a plurality of data lines extending in the column direction, to which a data signal is applied; a switching element disposed for each pixel corresponding to each of intersections formed by the gate lines and the data lines; a pixel electrode which is provided for each pixel and is connected to the switching element; first and second storage capacitor lines each provided for each row of the pixel electrodes, the first and second storage capacitor lines being different from the gate lines; and for a given pixel of the plurality of pixels, a storage capacitor formed by superposing a storage capacitor electrode connected to the switching element of the given pixel with the first or second storage capacitor line in the region of the given pixel, wherein the storage capacitor electrode extends to a region of an adjacent pixel in the row direction and uses a part of the region of the adjacent pixel for forming the storage capacitor; the first and second storage capacitor lines are provided for each gate line; the first and second storage capacitor lines are formed over a plurality of pixels arranged in the row direction; the storage capacitor is formed by superposing the storage capacitor electrode with respect to the first or second storage capacitor line in the region of the adjacent pixel; and the storage capacitor electrode extends to a region of an adjacent pixel in the row direction in parallel to the gate lines.
