Abstract
A liquid crystal display apparatus is provided which is capable of realizing a uniform display even at a high definition and offering a widened operating temperature. A signal line is formed on a signal line through an intervening insulating layer in an active-matrix type liquid crystal display apparatus of MIM drive type. MIM devices as two-terminal nonlinear devices are formed between each pixel electrode and the signal lines. The MIM devices are formed to operate in different operating temperature ranges. By selecting one of the signal lines to be supplied with a driving signal to achieve switching between the MIM devices, the pixel electrode associated therewith can operate within a wider operating temperature range. The respective resistances of the signal lines and/or MIM devices associated with each pixel electrode are adjusted so as to be equalized throughout all the pixel electrodes, thereby lessening a non-uniform display to ensure a uniform display.
