Abstract

An object of this invention is to make uniform the gap in the frame edge portion of the liquid crystal device and the wiring resistances and to improve the display quality and minimize the frame edge area to the limit. To achieve the above object, the liquid crystal display of this invention comprises a plurality of parallel display electrodes 40-n wired over the electrode substrate 311 (312); terminals 41-n for the electrodes 40-n led out to the end portion of the electrode substrate 311 (312) and connected to TCPs, the terminals 41-n having pitches smaller than those of the electrodes 40-n; and leadout wirings 331 (332) for connecting the electrodes 40-n and the terminals 41-n. The leadout wirings 331 (332) each consist of a portion extended from the respective electrode 40-n as it is, a portion extended from the respective terminals 41-n as it is, and almost parallel, inclined linear wiring 42-n that connects the two extended portions. The length of the two extended portions and the width of the inclined linear wiring 42-n are adjusted so that the wiring resistances of the individual leadout wirings 331 (332) are almost the same.
