发明名称 Metal-insulator-metal type active matrix liquid crystal display free from image sticking
摘要 A metal-insulator-metal liquid crystal display apparatus (i.e., MIM-LCD) which includes a liquid crystal display element having a lower substrate provided with a lead electrode, a pixel electrode and a MIM element connected between the lead and pixel electrodes. The LCD element also includes an upper substrate provided with a transparent counter electrode opposed to the pixel electrode. The MIM-LCD apparatus includes a constant resistor provided in series with the MIM element to prevent changes in the I-V characteristic of the MIM-element from affecting a driving voltage of the display. In an alternative embodiment, the LCD element includes a lower substrate provided with lead and pixel electrodes, an upper substrate provided with a transparent counter electrode opposed to the pixel electrode and a liquid crystal sandwiched between the upper and lower substrates. The LCD element of the second embodiment also includes first and second MIM elements connected in series with first and second constant resistors, respectively. The second MIM element has a higher resistance than the first MIM element and the second constant resistor has a lower resistance than the first constant resistor. The first MIM element and constant resistor are connected between the lead and pixel electrodes and in parallel with the second MIM element and constant resistor, to prevent image sticking.
