Filed: 2001-11-30
Abstract: <P>PROBLEM TO BE SOLVED: To provide an active matrix liquid crystal display device having a high contrast and high reliability without accompanying the increasing or the changing of the number of processes and the increasing of the number of masking sheets.  <P>SOLUTION: In this liquid crystal display device, the end part of the row direction of a reflection electrode 11 is more stretched out to the side of an adjacent reflection electrode 11 by a distance (t) than the end part of a source wiring 12. The distance (t) is decided so that light (L) from the gap of the reflection electrodes 11 does not reach a channel region 7a while generating multiple reflections between the source electrode 12 having high reflectance and the back surface of the reflection electrode 11. As a result, light incident on an insulator layer 10 does not reach the source electrode 12 and the possibility that multiply reflected light reaches the channel region 7a becomes low. Since the source wiring 12 is not exposed and the directly reflected light from itself of the source wiring 12 can be prevented, this device becomes possible to perform display having a high contrast in which the black is fastened by preventing vertical shadows (vertical stripe-shaped display failure) and the lowering of contrast.  <P>COPYRIGHT: (C)2003,JPO
