Abstract
In a liquid crystal display apparatus, a glass substrate has connection terminals and a stepped section at an edge thereof. A liquid crystal display panel is mounted on the glass substrate and is electrically connected to the connection terminals. A flexible printed board has leads and an insulating layer partly covering the leads. The connection terminals are adhered by a conductive adhesive agent to the leads, so that the stepped section of the glass substrate receives an edge of the insulating layer.
Claims8
A method for manufacturing a liquid crystal display apparatus, comprising the steps of:
- preparing a glass substrate having connection terminals;
- forming a stepped section at an edge of said glass substrate and adjacent to said connection terminals, wherein said stepped section comprises a wall adjacent to said connection terminals and an excess adhesive receiving surface extending from a base of said wall in a direction away from said connection terminals and towards said edge of said glass substrate;
- mounting a liquid crystal display panel on said glass substrate, said liquid crystal display panel being electrically connected to said connection terminals;
- coating a conductive adhesive agent on said connection terminals after said liquid crystal display panel is mounted;
- placing a flexible printed board having leads and an insulating layer covering a covered portion of said leads on said glass substrate, so that an exposed portion of said leads face said connection terminals, and an edge of said insulating layer faces said stepped section of said glass substrate;
- and
- applying pressure to said flexible printed board and said glass substrate, so that a connection section of said exposed portion of said leads are electrically connected via said conductive adhesive agent to said connection terminals, wherein said excess adhesive receiving section receives any excess portion of said conductive adhesive agent.
