Active matrix type display device and method of manufacturing the same
View Patent ↗A method of manufacturing an active matrix type display device, which is reliable and flexible, is provided. An active matrix type display device according to an aspect of the present invention includes: a first substrate, which is flexible; a thin glass layer provided on the first substrate via an adhesion layer, and having projections and depressions on a surface thereof opposing to the first substrate, the projections and depressions having rounded tips and bottoms; active elements provided on the thin glass layer, each active element corresponding to a pixel; a display provided above the thin glass layer, and driven by the active elements to display an image pixel by pixel; and a second substrate provided on the display, and having an opposing electrode formed thereon.
1. An active matrix type display device comprising:
a first substrate, which is flexible;
an adhesion layer provided on the first substrate;
a thin glass layer provided above the adhesion layer;
a compressive stress applying layer provided between the adhesion layer and the thin glass layer, the compressive stress applying layer applying a compressive stress to a surface of the thin glass layer at a side of the adhesion layer;
active elements provided on the thin glass layer, each active element corresponding to a pixel;
a display provided above the thin glass layer, and driven by the active elements to display an image pixel by pixel; and
a second substrate provided on the display, and having an opposing electrode formed thereon.
2. The active matrix type display device according to claim 1 , wherein a coefficient of linear expansion of the compressive stress applying layer is larger than a coefficient of linear expansion of the thin glass layer.
3. The active matrix type display device according to claim 2 , wherein the compressive stress applying layer is formed of a material selected from the group consisting of aluminum, silver, molybdenum, copper, and an alloy containing any of aluminum, silver, molybdenum, and copper.
4. The active matrix type display device according to claim 2 , wherein the compressive stress applying layer is formed of a material selected from a group consisting of lead glass and soda-lime glass.
5. The active matrix type display device according to claim 1 , wherein the first substrate is formed of a plastic.
