Axis-symmetric alignment achieved by using a mortarshaped pixel structure for fast switching twistedvertically aligned-mode reflective LCDs

Research output: Contribution to journalArticlepeer-review

Abstract

We have developed a fast switching twisted-vertically aligned (TVA)-mode reflective liquid crystal display (LCD) using a mortar-shaped pixel structure. We realized an axially symmetric pretilt angle in each pixel using the mortar-shaped pixel structure fabricated using UV pattern exposure. We experimentally confirmed that the axis-symmetric alignment from the mortar-shaped structure controls the start point of the alignment change in the voltage-on state over the entire surface of the pixel region, and is effective in improving the response speed of the TVA-mode LCD.
