<p>PROBLEM TO BE SOLVED: To diminish the load capacity of a driving circuit at the time of superposition of substrates and to enable high-speed driving by forming plural pixel transistors and part of their driving circuit and the electrodes corresponding to these pixel transistors and the other part of the driving circuit respectively in the same stages. SOLUTION: The liquid crystal driving circuit has the plural pixel transistors Tr arranged in a matrix form, the plural pixel electrodes D arranged in correspondence thereto, the perpendicular driving circuit 2 for driving the pixel transistors Tr successively along the perpendicular direction by a perpendicular clock Vclk and a dither reference voltage generating circuit 3 for generating the reference voltage corresponding to pixel positions by a horizontal clock Hclk and the perpendicular clock Vclk and inputting this voltage to a comparator C in order to execute dither modulation to a video signal Vsig. The counter substrate is provided with a horizontal driving circuit 1 for successively operating the plural selection switches SW along a horizontal direction by the horizontal clock Hclk. These substrates are formed in the respective same stages and are superposed on each other.</p> |
