Abstract
Disclosed is a transparent display apparatus. The transparent display apparatus includes a first substrate including a plurality of pixel areas, a first partition wall surrounding each of the plurality of pixel areas, a filling layer covering the first partition wall and the plurality of pixel areas, and a second substrate coupled to the filling layer. Accordingly, a stress applied to a display panel is reduced, and the peeling of an organic light emitting device and transmission of water are preventing from being spread, thereby enhancing the reliability of the display panel.
Claims20
A transparent display apparatus, comprising:
- a first substrate having thereon an emission part and a transmission part adjacent to the emission part;
- a subpixel provided in the emission part of the first substrate;
- a first partition wall adjacent to the subpixel and the transmission part;
- a second substrate opposite the first substrate;
- and
- a bank layer on the first substrate, the bank layer having a first bank layer portion and a second bank layer portion spaced apart from the first bank layer portion, the first bank layer portion having a first dimension that decreases as it extends toward the second substrate;
- wherein the first partition wall is on the first bank layer portion, the first partition wall including:
- a base partition wall on the first bank layer portion;
- and
- a protrusion partition wall on the base partition wall,
- wherein the base partition wall has a second dimension that increases as it extends toward the second substrate,
- wherein the protrusion partition wall has a third dimension that increases as it extends toward the second substrate,
- wherein the base partition wall and the protrusion partition wall are separate and distinct structures, and
- wherein the protrusion partition wall has a reverse tapered structure and the base partition wall has a reverse tapered structure.
