RD-15,727 LIGHT BLOCKING AND CELL SPACING STRUCTURE FOR LIQUID CRYSTAL MATRIX DISPLAYS Abstract of the Disclosure Light blocking spacer material is disposed so as to at least partially cover the data and/or gate lines in a variety of liquid crystal display (LCD) devices. The material prevents spurious visual information from being displayed as a result of high RMS supply voltages applied to the data lines, such voltages acting to switch liquid crystal material at inopportune times and to thus degrade the displayed image. The light block- ing material also enhances the displayed image by acting as a spacer between the front and back LCD device panels to insure uniform cell spacing. Light blocking material is also employed at the same time to prevent light from reaching light sensitive thin film field effect transistors (FETs) which operate to switch each cell or to establish gray levels therein. The light otherwise has a tendency to discharge the LCD cell, also hampering device function.
