ABSTRACT:
A matrix display device, for example an AMLCD, has first and second spaced substrates (22, 23) carrying opposed display pixel electrode structures (14, 32, 38) defining a pixel array/display area (20) with the first substrate (22) further carrying outside the display area auxiliary circuitry, for example, comprising row and column drive circuits (40, 42) a signal processing circuit (45) a memory circuit (47), or control logic circuit (46). At least a part of the auxiliary circuitry is electrical shielded to prevent electrical interference problems by an electrically conductive shielding layer(s) (60) carried on a part (50) of the first substrate (23) that extends over the auxiliary circuitry. The shielding layer may conveniently comprise part of an electrode layer (32) deposited on the second substrate and used for the pixel electrode structure.
