Abstract

An object of the present invention is an electro-optic device comprising a substrate holding an electro-optic substance; and a plurality of wirings having detour wiring portions formed on regions of the substrate other than the region facing the electro-optic substance. The detour wiring portion of each wiring described above has a first portion and a second portion narrower in width than the first portion. In the inspection process of the liquid crystal device having such a configuration, a plurality of inspection terminals for supplying predetermined drive signals to the respective wirings are brought into contact with the second portion of the respective wirings. Accurate inspection can be performed even when the intervals between wirings formed in the protruding area are narrow.

Description

[0001] The application for the present invention is a divisional application of the patent application with the same title filed on October 30, 2001 and with application number 01137595.7. technical field [0002] The present invention relates to an electro-optic device, its inspection method and an electronic device. Background technique [0003] As is well known, liquid crystal devices are widely used in display devices of various electronic devices such as mobile phones. The liquid crystal device includes: a pair of substrates bonded by a sealing material; a liquid crystal sandwiched between the two substrates; and a plurality of electrodes for applying a voltage to the liquid crystal. More specifically, it is generally configured such that a drive signal output from a driver IC mounted on a substrate, a flexible substrate, or the like is supplied to each electrode via wiring formed on the substrate. [0004] However, in the manufacturing process of such a liquid crystal...
