Abstract
A display apparatus including a plurality of pixel electrodes arranged in a matrix on a first substrate; a scanning line for sending a signal to the plurality of pixel electrodes for driving the plurality of pixel electrodes; a switching device for receiving the signal from the scanning line and switching each of the plurality of pixel electrodes into one of a conductive state and a non-conductive state in accordance with the signal; a counter electrode on a second substrate opposed to the first substrate; and a display medium layer sandwiched between the first substrate and the second substrate. The switching device includes a two-terminal element having a first electrode which is a part of the scanning line; the zinc sulfide layer on the first electrode, said zinc sulfide layer having an I-V characteristic expressed by a continuous curve; and a second electrode located on the zinc sulfide layer and electrically connected to the pixel electrode.
