Abstract
Abstract An electro-optical device comprising: an electro-optical panel having two substrates, at least one of which has a first group of lead terminals, a circuit board having a second group of lead terminals corresponding to the first group of the lead terminals, a connector for electrically connecting together the first and second groups of the lead terminals, a frame for positioning both the electro-optical panel and connector to the circuit board, and a buffer provided on at least a portion between the electro-optical panel and the frame.
