Abstract
Official abstract text for this publication.
A flexible wiring substrate includes a main substrate having flexibility, a main wiring disposed over the main substrate, a second protective sheet covering the main wiring, and an insulating member partially covering the main wiring exposed from the second protective sheet and being thinner in thickness than the second protective sheet.
First claim
Opening claim text (preview).
What is claimed is: 1 . A flexible wiring substrate, comprising: a base member having flexibility; a wiring disposed over the base member; a protective member covering the wiring; and an insulating member partially covering the wiring exposed from the protective member, and being thinner in thickness than the protective member. 2 . The flexible wiring substrate according to claim 1 , wherein in plan view of the base member, the insulating member partially overlaps the protective member. 3 . The flexible wiring substrate according to claim 2 , wherein the insulating member covers a side face of the protective member. 4 . The flexible wiring substrate according to claim 1 , wherein the insulating member includes a photosensitive resin material. 5 . The flexible wiring substrate according to claim 1 , wherein the insulating member includes a solder resist. 6 . The flexible wiring substrate according to claim 1 , comprising a plurality of terminals, wherein the insulating member is provided along a direction in which the plurality of terminals are aligned. 7 . The flexible wiring substrate according to claim 1 , wherein the protective member includes a polyimide. 8 . An electro-optical device, comprising: an electro-optical panel including a semiconductor substrate and a panel-side terminal provided along one side of the semiconductor substrate; and the flexible wiring substrate according to claim 1 , wherein a wiring of the flexible wiring substrate is electrically coupled with the panel-side terminal. 9 . The electro-optical device according to claim 8 , wherein the insulating member included in the flexible wiring substrate contacts a corner portion of a side face of the semiconductor substrate. 10 . An electronic apparatus, comprising the electro-optical device according to claim 8 .
