Abstract:
An active matrix display device, comprising:an array substrate containing pixel electrodes disposed, via switching elements, in the vicinity of respective crossing points of mutually crossing plural signal lines and plural scanning lines;a counter electrode opposed to the pixel electrodes;a display panel containing a light modulating layer controlled on the basis of a potential difference between the counter electrode and the pixel electrodes;a video signal supply configured to apply a video signal voltage to the plural signal lines;a scanning signal supply configured to supply a scanning signal having a first voltage configured to turn on the switching elements and a second voltage configured to turn off the switching elements to the plural scanning lines; anda counter electrode driver configured to supply a counter electrode voltage to the counter electrode;wherein the array substrate includes,a scanning line connector which electrically connects the plural scanning lines mutually via a first nonlinear element and which is electrically connected to the counter electrode driver, anda first nonlinear resistance circuit configured to adjust the counter electrode voltage applied to the scanning line connector substantially to the second voltage;wherein when a high voltage is applied to the plural scanning lines, the first nonlinear element is turned on and an electric charge on the plural scanning lines is thereby dispersed through the scanning line connector, andthe first nonlinear resistance circuit brings the scanning line connector to substantially the second voltage, thereby reducing a potential difference from the plural scanning lines and turning off the first nonlinear element.
