Abstract
A pair of storage capacitor electrodes are extended along a data line to provide storage capacitance along the data line. One of the storage capacitor electrodes is a metal electrode which partially overlaps the data line. Light can thereby be shielded in a region between the data line and a pixel electrode while forming a storage capacitor. The other storage capacitor electrode is positioned so as to avoid overlapping the data line, thereby suppressing coupling between the data line and the other storage capacitor electrode.
Claims18
An active matrix display device in which display in each pixel is controlled by switching a transistor disposed in each pixel, comprising:
- a plurality of gate lines arranged in a column direction;
- a plurality of data lines arranged in a row direction;
- pixel electrodes arranged in a matrix corresponding to each intersection of said gate lines and said data lines;
- a first storage capacitor electrode connected to said pixel electrode;
- a second storage capacitor electrode extended in a direction parallel to said gate lines, said second storage capacitor electrode opposing said first storage capacitor electrode beyond an insulating film, and forming a storage capacitor in said opposed portion;
- wherein
- portions of said first and second storage capacitor electrodes protrude along said data line in a direction parallel to said data lines;
- and
- at least a part of a protruding portion of said first storage capacitor electrode and a part of a protruding portion of said second storage capacitor electrode are overlapped.
