An improved electrooptic ceramic reflective display is depicted utilizing polished plates of PLZT ceramic materials in a specific arrangement of dual polarizers, PLZT plate, dual transparent electrode patterns deposited on each major surface in precise alignment of the PLZT plate, and a reflecting surface. The display achieves an optimum effect of high contrast of the associated characters, good brightness, wide viewing angle, and minimum operating voltage requirements. When no voltage is applied, the display has a uniform brightness with no characters shown. When a segment, character, or group of characters is activated by applying a selective voltage, a transverse electrooptic effect is electrically induced and a dark character on a light background is depicted. An elastomer Zebra type connector bar is slit and is utilized to facilitate the electrical connections to the top and bottom electrode pads of the PLZT plate as well as to the associated circuitry for the assembled display.
