Abstract

In a TFT type liquid crystal display device comprising first and second transparent substrates and a liquid crystal layer which is sandwiched between the first and second substrates, the first substrate includes a plurality of video signal lines, a plurality of scanning signal lines and a plurality of pixel regions which are formed as regions surrounded by the video signal lines and the scanning signal lines, each pixel region includes at least one active element, one pixel electrode and one common electrode, and color filter layers are formed between the pixel electrodes and the liquid crystal layer. The liquid crystal display device is substantially characterized in that the common electrodes are formed as layers above the color filters, the pixel electrodes are formed as layers below the color filters, and the color filters are superposed at least on the whole surfaces of the pixel electrodes in the pixel region.
