1. Field
The present disclosure relates to a substrate and a display device including the substrate.
2. Description of the Related Technology
A display device such as an organic light emitting device and a liquid crystal display (LCD) may include a substrate.
The substrate for a display device may in general include a glass substrate, a plastic substrate, or the like.
However, a glass substrate may be damaged by an external impact as well as have a limit in achieving a portable display and a large screen since the glass substrate is heavy and fragile. Thus, it may not be appropriate to include in a flexible display device.
The plastic substrate may have an advantage of portability, safety, and lightness when compared with a glass substrate. In addition, since the plastic substrate is fabricated through deposition or printing, manufacturing cost may be lowered. Since a display device including the plastic substrate may be fabricated in a roll-to-roll process rather than a conventional sheet unit process, it may be produced in high volume with a low cost.
However, there may be disadvantages to using a plastic substrate in a display device. For example, the plastic substrate may be deteriorated due to permeability and oxygen transmission of a plastic material and thermal decomposition at a high temperature due to weak heat resistance having a negative influence on a device.
