Abstract

An apparatus for manufacturing a bending panel of a display includes a lower mold having a first member on which a target panel is placed, an upper mold disposed adjacent the lower mold and including a second member including a first surface to press a portion of the target panel and a second surface having a first slope with respect to the first surface, and side molds disposed at opposite sides of the lower mold and each having a third member with a third surface complementary to the second surface of the second member. The first slope is smaller than about 90 degrees.

First claim

What is claimed is:
