    摘要： An active matrix type liquid crystal display apparatus, including a pair of substrates and a liquid crystal layer interposed between said pair of substrates. One of the pair of substrates has plural scanning electrodes and plural signal electrodes arranged to cross the plural scanning electrodes. Pixels are formed at regions surrounded by the scanning electrodes and the signal electrodes. Respective ones of the pixels include an active element arranged at a vicinity of the crossing point of the scanning electrode and the signal electrode, a pixel electrode connected to the active element and a common electrode arranged in correspondence to the pixel electrode. Further, there is provided a colored filter and a shielding layer having a specific resistivity of less than 108 &OHgr;.cm.

    摘要： The present invention provides an image display capable of performing high-precision multi-gradation display while avoiding problems of a subtle noise and increase in a drive frequency. Display signal data of one frame is constructed by a plurality of sub frames of, for example, four sub frames 1/4 to 4/4. The 1/4 frame is set as an address period of an analog signal, the 2/4 frame is set as an analog gradation display period, the 3/4 frame is set as an address period of a digital signal, and the 4/4 frame is set as a digital gradation light emission period. The image display is constructed in such a manner that, in the analog gradation display period, an OLED device in a pixel emits light of time according to an analog signal voltage stored in a storage capacitor in the pixel by an analog drive signal circuit and, in the digital gradation display period, a binary light emitting operation of light emission and non light emission is performed according to a digital signal voltage stored in the storage capacitor by a digital signal driving circuit.
