Classification: CPC H | IPC H

Claim 13:
14. A method of manufacturing a display apparatus comprising a main display area, a component area comprising a transmission area, and a peripheral area located outside the main display area, the method comprising:
preparing a second substrate;
forming a first inorganic layer on the second substrate;
forming a second inorganic layer on the first inorganic layer;
forming a first substrate on the second inorganic layer and the first substrate comprising transparent polyimide;
forming a barrier layer having a density ranging from about 2 g/cm3 to about 6 g/cm3 on the first substrate;
forming a buffer layer on the barrier layer; and
forming a main pixel circuit comprising a first semiconductor layer located on the buffer layer to correspond to the main display area and an auxiliary pixel circuit comprising a second semiconductor layer located on the buffer layer to correspond to the component area,
wherein the barrier layer comprises one material from among a nitrogen rich silicon nitride (SiNx) having low or no hydrogen content with x being greater than 4/3, a silicon nitride (Si3N4) having low or no hydrogen content, and zirconium oxide (Zr2O3).
