Flexible display apparatus and method of manufacturing the same

A method of manufacturing a flexible display apparatus, the method comprising:

• forming a sacrificial layer on a support substrate;
• forming a first material layer having a higher hydrogen concentration than the sacrificial layer on the sacrificial layer;
• forming, on the first material layer, a second material layer preventing hydrogen from diffusing to a side opposite of a side on which the sacrificial layer is located;
• forming a display layer on the second material layer;
• and
• irradiating a laser onto the support substrate to delaminate the sacrificial layer from the first material layer.

A flexible display apparatus, comprising:

• a first material layer including silicon nitride (SiNx);
• a barrier layer on the first material layer;
• a second material layer between the first material layer and the barrier layer to prevent hydrogen from diffusing from the first material layer into the barrier layer;
• and
• a display layer on the barrier layer.
