  • Patent number: 4470667
    Abstract: A display apparatus comprises a first substrate provided with a thin film transistor array as a driving switching element and a second substrate provided with another electrode, and produces a display by electro-optical change generated between these substrates. Visibility of the display is improved in such a way that rays of light incident on the display apparatus are converted into diffusion light. Photoconductive material, in particular amorphous silicon, can be used by covering semiconductive portions of the thin film transistor array of the display apparatus with an intercepting member. In a display apparatus using a thin film transistor array as a driving switching element, a conductive surface electrically insulated from gate lines on a substrate on where the gate lines for the thin film transistor array are formed, such conductive surface acts as a counter electrode of capacitors for storing charge.
