Abstract

A display apparatus may include a base substrate including a first portion and a second portion smaller than the first portion, a plurality of pixels disposed on the first portion, a protection substrate disposed below the base substrate, and a groove disposed in a portion of the protection substrate and overlapped with the second portion. The groove may include a first region extending in a first direction, and a second region and a third region, which are arranged along the first direction, wherein the first region is interposed between the second region and the third region. The first and second portions may be arranged in a second direction crossing the first direction, and a width of each of the second and third regions may be larger than a first width of the first region, when measured in the second direction.

First claim

What is claimed is:

1. A method of fabricating a display apparatus, comprising:
receiving a display panel including a base substrate with a first portion and a second portion, a protection substrate disposed below the base substrate, and a plurality of pixels disposed on the first portion, the second portion being smaller than the first portion and including a bending region extending in a first direction;
irradiating an ultraviolet laser beam to a dummy region, which is a region of the protection substrate overlapped with the second portion, and irradiating a carbon dioxide laser beam to a border of the dummy region;
delaminating the dummy region from the base substrate; and
bending the bending region,
wherein the dummy region comprises:
a first region extending in the first direction; and
a second region and a third region, which are arranged along the first direction,

wherein the first region is interposed between the second region and the third region,
the bending region is overlapped with the first region and is extended in the first direction,
the first and second portions are arranged in a second direction crossing the first direction when the display apparatus is in an unbent state, and
a width of each of the second and third regions is larger than a width of the first region, when measured in the second direction when the display apparatus is in the unbent state.

2. The method of claim 1 , wherein the delaminating of the dummy region starts from one of the second and third regions.
