Abstract

A method for manufacturing a liquid crystal display device including a first substrate and a second substrate, each of the first substrate and the second substrate having flexibility, the method includes a first step of manufacturing a display panel having flexibility, the display panel including the first substrate and the second substrate, a second step of bending the display panel such that a display of the display panel is constructed with a first flat surface and a second flat surface and a curved surface disposed between the first flat surface and the second flat surface, the curved surface having a predetermined curvature radius; and a third step of fixing the display panel subjected to the second step to a cover member keeping the curved surface in a given shape.

Claims (7)

1. A method for manufacturing a liquid crystal display device including a first substrate and a second substrate, each of the first substrate and the second substrate having flexibility, the first substrate and the second substrate being disposed opposite to each other, the method comprising:

a first step of manufacturing a display panel having flexibility, the display panel including the first substrate and the second substrate;

a second step of bonding a first polarizing plate to a first surface of the display panel while bonding a second polarizing plate including an extension unit projecting outward from the first polarizing plate in plan view to a second surface of the display panel;

a third step of covering a jig in which a leading end is formed into a predetermined curvature radius with the display panel subjected to the second step, of bringing the extension unit into close contact with the display panel while pulling the extension unit, and of bending the display panel such that a display of the display panel is constructed with a first flat surface and a second flat surface and a curved surface disposed between the first flat surface and the second flat surface, the curved surface having a predetermined curvature radius; and

a fourth step of fixing the display panel subjected to the third step to a cover member keeping the curved surface in a given shape.

2. The method for manufacturing the liquid crystal display device according to claim 1 , wherein the first flat surface and the second flat surface are disposed parallel and opposite to each other.

3. The method for manufacturing the liquid crystal display device according to claim 1 , wherein the display panel is bent such that the curvature radius of the curved surface becomes 50 mm or less.
