Active matrix substrate and method of manufacturing the same
First Claim
1. An active matrix substrate comprising:
- a substrate;
a position control member provided on said substrate and having an opening at a central portion thereof to expose a top surface of said substrate, said opening being surrounded by a sidewall of said position control member, said position control member having an inner side face which inclines at a specific angle with respect to said substrate;
an active element provided on said position control member;
a fitting member abutting a bottom surface of said active element and configured to engage with said inner side face of said position control member and an outer side face of said fitting member has at least a part that inclines at substantially the same angle as said specific angle of said inner side face of said position control member with respect to said substrate; and
an adhesion section which includes an adhesive that bonds said active element to said substrate or said position control member and whose wettability with said position control member is lower than that of said adhesive with said substrate.

Abstract
An active matrix substrate comprises a substrate, a position control member provided on the substrate and surrounding a specific space by a sidewall thereof to expose a surface of the substrate and whose inner side face inclines at a specific angle with respect to the substrate, an active element provided so as to engage with the inner side face of the position control member and whose outer side face has at least a part that inclines at substantially the same angle as the specific angle of the inner side face of the position control member with respect to the substrate, and an adhesion section which bonds the active element to the substrate or the position control member and whose wettability with the position control member is lower than that of the adhesive with the substrate.
