摘要： In a liquid crystal projection color display apparatus having three liquid crystal display devices used for red, green and blue lights, each liquid crystal display device has a liquid crystal display panel and a microlens array disposed on the light-source side or the light-source and screen sides of the liquid crystal display panel. The microlens array has a controllable refractive power by applying an electric power. An electric voltage is applied between transparent electrodes formed on both surfaces of a microlens array so that the refractive power of the microlens array can be made a value adapted to suit the corresponding one of red, green and blue lights.

摘要： An improved arrangement of a liquid crystal display device is provided in which the redundancy of known but unwanted TFT (thin film transistor) defect is suppressed so that the yield per finished liquid crystal display device products can be increased without declination in the picture quality. Each pixel of the liquid crystal display device arranged at an intersection of one of scanning lines and one of signal lines is provided with two or three TFTs and also, a storage capacitor which is formed of a portion of a gate insulating layer sandwiched between its electrode and a preceding scanning line in the previous row with using no extra masking procedure. The source, drain and gate electrodes of both the first and third TFTs are coupled to the same signal line, the electrode of the same pixel and the adjacent scanning lines, respectively. The gate, source and drain electrodes of the second TFT are coupled respectively to the same scanning line to which the gate electrode of the first TFT is coupled, the electrode of the same pixel and the electrode of a succeeding pixel provided on the opposite side of the scanning line to the same pixel. The arrangement also has a scanning driver circuit capable of activating two scanning lines at the same time for sequential one-by-one scanning operation, whereby no fault in a reproduced image will be perceived in spite of the presence of a defective TFT.
