Abstract:
A display device having at least an active matrix panel, the active matrix panel comprising:a first transparent substrate; a second transparent substrate arranged opposite to the first transparent substrate; a liquid crystal material arranged between the first and second transparent substrate, wherein the first transparent substrate includes, a plurality of gate lines, a plurality of source lines, a plurality of pixel thin film transistors formed in intersections of the gate lines and the source lines, a gate line driver circuit formed of first thin film transistors and connected to the gate lines, a source line driver circuit formed of second thin film transistors and connected to the source line, a processing circuit having a function of mask-processing to decrease noise of an image, the processing circuit comprising: a standard clock generator circuit having third thin film transistors, a counter circuit having fourth thin film transistors, and a clock generator separate from said standard clock generator circuit and controlling at least one of the gate line driver circuit and the source line driver circuit, wherein said counter circuit is controlled by a clock signal generated in said standard clock generator, and wherein said counter circuit is a circuit designating an address of pixels to be mask-processed.
