Patent ID: 8358259

Claim:
A liquid crystal display device, comprising: a pair of substrates which are arranged to face each other in an opposed manner with liquid crystal sandwiched therebetween; a plurality of gate signal lines and a plurality of drain signal lines which are formed on one substrate in a matrix array; a plurality of pixel regions defined by the gate signal lines and the drain signal lines; and a reference electrode and a pixel electrode which are formed in the inside of each pixel region, wherein: the plurality of pixel regions are formed in both a display region and a non-display region, a voltage applied to the reference electrodes is applied to the pixel electrodes in the inside of the pixel regions in the non-display region, the pixel electrodes in the pixel regions in the inside of the non-display region do not include thin film transistors, reference voltage supply signal lines for applying the reference voltage to the pixel electrode in the pixel regions in the inside of the non-display region connect directly to the pixel electrodes, the reference voltage supply signal lines are formed in parallel to the drain signal lines, and a line width of the reference voltage supply signal lines is larger than a line width of the drain lines.
