1. A television communication apparatus comprising:
- (a) a displaying/imaging apparatus disposed to face an operator comprising;
a pair of spaced apart substrates which define an internal volume therebetween, at least one of the substrates being light transmissive;
a matrix of pixel electrodes mounted on a volume-oriented side of at least one of the substrates;
at least one light-receiving element of an imaging device mounted within the internal volume;
a discrete light receiving electrode having means for adjusting the amount of light received by the light-receiving element;
a dielectric interposed within the internal volume, the dielectric providing a display function in accordance with activation of the pixel electrodes;
(b) image driving means for receiving an image signal through a communication line and providing the pixel electrodes with the image signal to perform a display operation;
(c) a speaker;
(d) an audio driving circuit for receiving an audio signal through the communication line and driving the speaker;
(e) a microphone; and
(f) transmitting means for transmitting outputs from the outputting means and the microphone to the communication line.

Abstract
In a picture telephone, an apparatus is provided which images the face of an operator in a natural manner for a conversation, with an eye height at which the operator looks at an image expressing a partner of the conversation. A number of photodiodes are disposed each adjacent to each pixel electrode, on surfaces facing each other of a pair of substrates between which a liquid crystal of a transmission type active matrix liquid crystal display apparatus is interposed. Outputs from the respective photodiodes are read out by a so-called inter-line transmission method which utilizes a scanning function of a CCD (charge coupled device).
