ABSTRACT:
A liquid crystal display apparatus which performs a display by modulating an optical characteristic of a display medium, includes: a plurality of pixel electrodes for allowing the display medium to perform a display in accordance with a display signal; switching elements, respectively provided for the corresponding pixel electrodes, for applying the display signal to the respective pixel electrodes in nonlinearly response to a received driving signal; and a bus line for applying the driving signal to the switching elements. Each of the switching elements includes a first active device and a second active device. The first active device includes a lower electrode connected to the corresponding one of the pixel electrodes, an upper electrode connected to the bus line, and a nonlinear resistive layer interposed between the lower electrode and the upper electrode. The second active device includes a lower electrode connected to the bus line, an upper electrode connected to the corresponding pixel electrode, and a nonlinear resistive layer interposed between the lower electrode and the upper electrode. Each of the nonlinear resistive layers of the first and the second active elements contains zinc sulfide as its main component.
