Electro-optical device and electronic apparatus
An electro-optical device includes an electro-optical panel including a pair of first panel alignment marks having a first shape and a pair of second panel alignment marks having a second shape; a first circuit substrate provided with a first circuit substrate alignment mark which is represented by the first shape in plan view; and a second circuit substrate provided with a second circuit substrate alignment mark which is represented by the second shape in plan view.
1. An electro-optical device comprising:
an electro-optical panel including:
a first terminal portion on which a plurality of terminals are arranged in a predetermined direction;
a pair of first panel alignment marks having a first shape provided in both end sides for the predetermined direction of the first terminal portion
a second terminal portion on which a plurality of terminals are arranged in the predetermined direction; and
a pair of second panel alignment marks having a second shape provided in both end sides for the predetermined direction of the second terminal portion, the second shape being different from the first shape in a direction of a characteristic portion thereof or being different from the first shape in a shape thereof; and
a first circuit substrate provided with a first connection terminal portion electrically connected to the first terminal portion, the first circuit substrate being provided with a first circuit substrate alignment mark which is represented by the first shape in plan view, which is not overlapped each other upon superimposing the first panel alignment mark in a reference position, and which is set as the predetermined shape in a shape upon incorporation; and
a second circuit substrate provided with a second connection terminal portion electrically connected to the second terminal portion, the second circuit substrate being provided with a second circuit substrate alignment mark which is represented by the second shape in plan view, which is not overlapped each other upon superimposing the second panel alignment mark in a reference position, and which is set as the predetermined shape in a shape upon incorporation.
