Abstract
In a display device connected with an IC driver, particularly the reliability of connection between an IC terminal located on the outermost side and the IC driver is improved. IC terminals and flexible wiring board terminals are formed on a terminal region of a TFT substrate. A plurality of the IC terminals are formed at a predetermined pitch. The reliability of an outermost IC terminal is degraded as compared with the reliability of the other IC terminals caused by the loading effect in etching a protection insulating film. In order to prevent this degradation, a dummy terminal is formed on the outer side of the outermost IC terminal, and the loading effect on the outermost IC terminal is made equal to the loading effect on the other IC terminals. Accordingly, degradation in the reliability of the outermost IC terminal is prevented.
