Abstract

According to one embodiment, a substrate for a display includes: one surface; the other surface opposite to the one surface; a first region; and a second region in which one surface is folded to face itself, the first region being defined as a folded region, and the second region being defined as an unfolded region. The substrate for a display includes a first layer and a second layer disposed on the first layer, in which a first region of the first layer includes a plurality of first holes or first grooves, the first layer is an etching layer, and the second layer is an etching stop layer.

Description

technical field [0001] The embodiment relates to a substrate for a display. Background technique [0002] Recently, there is a growing demand for flexible or foldable display devices capable of easily executing various applications and displaying images on a large screen while being carried. [0003] Such flexible or foldable displays are folded or partially bent when being carried or stored, and can be implemented with unfolded displays when displaying images. Therefore, the image display area can be increased, and the user can easily carry the display. [0004] After the flexible or foldable display device is folded or bent, the restoration process of unfolding the flexible display device again may be repeated. [0005] That is, since the flexible or foldable display device repeats folding and unfolding operations, the substrate of the flexible display device is required to have certain strength and elasticity, and cracks and deformations should not occur in the substrat...
