1. A flexible display apparatus comprising:
- a substrate;
a display unit for displaying an image and located on the substrate;
a non-display area located on the substrate and formed outside the display unit, the non-display area comprising;
a stiffener comprising a plurality of reinforcement lines formed on the substrate and patterned to reduce or prevent thermal deformation of the substrate;
at least one pad formed on and electrically insulated from each of the reinforcement lines; and
a stiffener insulating layer between the reinforcement lines and the at least one pad, the stiffener insulating layer being configured to electrically insulate each of the reinforcement lines from the at least one pad; and
a circuit board comprising circuit terminals to be electrically connected to the at least one pad,wherein the reinforcement lines are arranged apart from one another by a first distance in one direction of the substrate and are arranged in another direction of the substrate to constitute an aggregate having a regular pattern,wherein the display unit comprises an organic light-emitting display apparatus comprising;
a semiconductor active layer having a source/drain region and a channel region;
a gate insulating layer formed on the semiconductor active layer;
a gate electrode formed on the gate insulating layer;
an interlayer insulating layer formed on the gate electrode and having a contact hole formed in the interlayer insulating layer;
a source/drain electrode that is electrically connected to the source/drain region;
a protective layer comprising a passivation layer and/or planarization layer formed on the interlayer insulating layer; and
a display device,wherein the at least one pad is electrically connected to the gate electrode or the source/drain electrode,wherein the at least one pad is patterned of a same material as a material for forming the source/drain electrode, andwherein the stiffener is patterned of a same material as a material for forming the gate electrode.

Abstract
A flexible display apparatus is disclosed. The flexible display apparatus includes: a substrate on which a display unit for displaying an image, a non-display area formed outside the display unit, and at least one pad for inputting an electrical signal to the display unit are located; and a circuit board including circuit terminals to be electrically connected to the at least one pad. A stiffener including a plurality of reinforcement lines that are patterned to reduce or prevent thermal deformation of the substrate is formed on the substrate.
