Abstract

Provided is an electro-optical device that simplifies a terminal connection process and can enlarge the area ratio of a display area. The connecting terminal portion connected to the scanning driver IC chip (32) is arranged on the short side portion of the wiring bonding region (25A) of the second substrate (25) in the liquid crystal display panel (21), and the connecting terminal portion and the arrangement The bonding terminal portion on the long side of the wiring bonding region (24A) of the first substrate (24) is bonded to one flexible printed wiring substrate (22) from the same direction.

Description

technical field [0001] The present invention relates to electro-optical devices such as liquid crystal devices, EL (Electroluminescence) electro-optical devices, and the like. The present invention also relates to a flexible printed wiring board used in the electro-optical device and electronic equipment equipped with the electro-optical device. Background technique [0002] In recent years, electro-optical devices have been widely used as portable devices and information display terminals in homes, offices, factories, automobiles, and the like. In particular, liquid crystal display devices have the characteristics of being thin, light in weight, low in voltage, and low in power consumption. Therefore, liquid crystal display devices will exist as the main body of electronic displays now and in the future, and are increasingly widely used in PDAs (Personal Portable Information Terminals) and the like due to low power consumption. [0003] As a conventional liquid crystal di...
