摘要:
An organic black matrix having high resistivity (.gtoreq.10.sup.11 ohm/square), high optical density (.gtoreq.2.0) at ultra thin film thicknesses (.ltoreq.1.0 microns) for improved STN and TFT pixel display applications is made possible by combining polyimide/dye solutions and mixed metal oxide pigment dispersions at a weight/weight ratio of dye to pigment of 1:15 to 3:15. The need for low resistivity carbon black, as a replacement for sputtered chrome, is negated.
