Abstract: Regarding a liquid crystal device having a structure in which electrodes formed on a pair of substrates are subjected to conductive connection using a conductive member, the outer dimensions can be reduced despite the use of the conductive member, and a complicated pattern design including cross wiring and the like can be employed for the electrode patterns formed on the pair of substrates. A liquid crystal device is formed by joining a first substrate 2a comprising first electrodes 7a and external joining elements 8 and a second substrate 2b comprising second electrodes 7b by an annular sealing member 3. The sealing member 3 includes a conductive section 3b having the function of conductive connection and a non-conductive section 3a having no function of conductive connection, and the second electrodes 7b on the second substrate 2b are individually subjected to conductive connection to the terminals 8 on the first substrate 2a via the conductive section 3b of the sealing member 3.

Abstract: A display device including a pair of opposed substrates at least one of which is transparent with a display medium layer therebetween, and a transparent electrode arranged on the internal surface of the transparent substrate is provided. The thickness of the transparent electrode is about ((5500.times.N)/(2.times.n)).ANG. wherein N is a natural number and n represents the refractive index thereof.
