Abstract
An organic light-emitting display device and manufacturing method thereof is capable of preventing the stretching of the organic light-emitting display device through a rolling process of attaching a support film.
Claims18
An organic light-emitting display device comprising:
- a flexible substrate including a display area, a bending area, and a pad area;
- a pixel array layer disposed on an upper surface of the flexible substrate;
- an adhesive layer and a backplate disposed on a lower surface of the flexible substrate;
- a polarizing plate disposed on the upper surface of the pixel array layer;
- and
- a flexible printed circuit board attached to the pad area,
- wherein the backplate includes a mesh pattern inserted into an interior thereof, and
- wherein the mesh pattern is disposed adjacent to the flexible substrate within the backplate to contact the adhesive layer, and a distance between the mesh pattern and the adhesive layer is shorter than a distance between the mesh pattern and a lower surface of the backplate.

A method of manufacturing an organic light-emitting display device, the method comprising:
- forming a flexible substrate on a mother substrate;
- forming a pixel array layer on the flexible substrate;
- separating the mother substrate;
- attaching a support film comprising a mesh pattern to the flexible substrate;
- attaching, after attaching the support film, a polarizing plate and a flexible printed circuit board;
- and
- bending the organic light-emitting display device,
- wherein the support film comprises an adhesive layer and a backplate, and the mesh pattern is inserted into an interior of the backplate;
- and
- wherein the mesh pattern is disposed adjacent to the flexible substrate within the backplate to contact the adhesive layer, and a distance between the mesh pattern and the adhesive layer is shorter than a distance between the mesh pattern and a lower surface of the backplate.
