ABSTRACT:
A display apparatus includes two substrates having electrodes, respectively, and a liquid crystal layer arranged between the two substrates. One of the two substrates includes a plurality of linear luminous sources ranged in parallel each other, a plurality of linear electrodes ranged in parallel each other and the linear electrodes being crossed with the plurality of linear luminous sources, and a plurality of photoconductive layers provided at crossed positions of the plurality of linear luminous sources and the plurality of linear electrodes, the photoconductive layers serving to perform switching operation in response to light applied from the plurality of linear luminous sources. The liquid crystal has pixels to be driven by a signal applied through the plurality of linear electrodes and the plurality of photoconductive layers.
