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.
