[0007]One aspect of the present invention provides a substrate for a thin, flexible display, which has film stress range that does not affect an electronic device, su

Problems solved by technology

The displays of mobile devices need to be thin, light, and moreover, unbreakable.
However such methods are complicated and the glass substrate may easily break, and thus the methods are difficult to be actually used.
However, it is difficult for the conventional g

Abstract

A substrate for a flexible display is disclosed. The substrate has a film stress range that does not affect an electronic device such as a thin film transistor, and includes a barrier layer having excellent oxygen and moisture blocking characteristics, and a method of manufacturing the substrate. The substrate includes: a plastic substrate having a glass transition temperature from about 350° C. to about 500° C.; and a barrier layer disposed on the plastic substrate, having a multi-layer structure, wherein at least one silicon oxide layer and at least one silicon nitride layer are alternately stacked on each other, and having a film stress from about −200 MPa to about 200 MPa due to the at least one silicon oxide layer and the at least one silicon nitride layer.

Description

CROSS-REFERENCE TO RELATED PATENT APPLICATION[0001]This application claims the benefit of Korean Patent Application No. 10-2010-0074979, filed on Aug. 3, 2010, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present disclosure relates to a substrate for a flexible display, and a method of manufacturing the substrate.[0004]2. Description of the Related Art[0005]Markets of liquid crystal display devices and organic light emitting display devices are currently expanding to displays of digital cameras, video cameras, and mobile devices, such as personal digital assistants (PDAs) and mobile phones. The displays of mobile devices need to be thin, light, and moreover, unbreakable. In order to form a thin and light display, a method of preparing a display by using a conventional glass substrate, and then thinning the glass substrate mechanically or chem...
