Abstract
In an active matrix type display device using TFTs as switching elements, in order to remarkably improve the aperture ratio and, at the same time, largely lower a dissipation power, an extending electrode is provided as one unit to a scanning line and light is shut off at those areas between a signal line and two display pixel electrodes situated adjacent the signal line, the two display pixel electrodes being arranged with the signal line interposed.
Claims17
An active matrix type display device comprising:
- a light-transmitting substrate;
- scanning lines formed on the light-transmitting substrate;
- signals lines formed to intersect the scanning lines and insulated from the scanning lines;
- a matrix array of capacitance drive type pixels formed near intersections of the scanning lines and signal lines, each capacitance drive type pixel having a display pixel electrode and a thin film transistor connected between a corresponding signal line and the display pixel electrode;
- and
- extending electrodes that are electrically connected to the scanning lines and extend from the scanning lines along the signal lines, each extending electrode being capacitively coupled to the corresponding signal line and a display pixel electrode that is adjacent to the corresponding signal line by overlapping a portion of the adjacent display pixel electrode and the corresponding signal line.
