摘要:
The present invention provides a display apparatus that can reduce a voltage irregularity and a brightness irregularity accompanied by making an enlarged and a high resolution type display apparatus. The display apparatus comprises plural pixel electrodes 5 arranged in a matrix, a switching element 3 connected with the pixel electrode, a scanning electrode 1, a picture signal electrode 2, an opposite electrode forming a capacitance with the pixel electrode 5, and further comprising; a storage capacitance 7 between the pixel electrode 5 and the scanning electrode 5 other than the scanning electrode 1 of the present line; more than two capacitance elements connected with the pixel electrode 5, including at least one of a gate-drain inter-electrode capacitance 4 of the switching element 3 and the storage capacitance 7, having a different value according to the distance from the power feeding edge of the scanning electrode 1; wherein, each capacitance in each pixel is set so that, when all capacitance connected with the pixel electrode 5 in a pixel is denoted as Ctot, a first capacitance ratio α gd=Cgd/Ctot increases continuously or in stages according to the distance from the power feeding edge of the scanning electrode 1, or a second capacitance ratio α st=Cst/Ctot is substantially constant.
