Organic light-emitting display apparatus
An organic light-emitting display apparatus includes: a substrate including a display area and a peripheral area outside the display area; an alignment mark located in the peripheral area; and an insulating film located in the peripheral area and including a first opening through which at least a part of the alignment mark is exposed and a plurality of slits that extend from the first opening.
1. An organic light-emitting display apparatus comprising:
a substrate comprising a display area and a peripheral area outside the display area;
an alignment mark located in the peripheral area; and
an insulating film located in the peripheral area and comprising a first opening through which at least a portion of the alignment mark is exposed and a plurality of slits that extend from the first opening,
wherein each of the plurality of slits extends from a bottom of the insulating film through a top of the insulating film.
2. The organic light-emitting display apparatus of claim 1 , wherein the first opening has a shape corresponding to the alignment mark.
3. The organic light-emitting display apparatus of claim 1 , wherein an inner surface of the first opening is spaced apart from an edge of the alignment mark.
4. The organic light-emitting display apparatus of claim 3 , wherein the first opening has a quadrangular shape.
5. The organic light-emitting display apparatus of claim 1 , wherein the plurality of slits extend up to an edge of the substrate.
6. The organic light-emitting display apparatus of claim 1 , wherein the alignment mark has an edge that is inclined downward.
7. The organic light-emitting display apparatus of claim 1 , further comprising:
a pixel electrode located in the display area; and
a thin-film transistor comprising a conductive pattern that is electrically coupled to the pixel electrode,
wherein the alignment mark comprises the same material as a material of the conductive pattern.
8. The organic light-emitting display apparatus of claim 7 , wherein the insulating film is located over the display area and the peripheral area, and
wherein the insulating film is located on a lower layer under the pixel electrode and comprises a second opening through which at least a central portion of the pixel electrode is exposed.
9. The organic light-emitting display apparatus of claim 7 , further comprising a pixel-defining film located in the display area and comprising a second opening through which at least a central portion of the pixel electrode is exposed,
wherein the insulating film comprises the same material as a material of the pixel-defining film.
10. The organic light-emitting display apparatus of claim 1 , wherein the insulating film is located in the display area and the peripheral area, and
wherein a portion of the insulating film located in the display area and a portion of the insulating film located in the peripheral area are separate from each other.
11. The organic light-emitting display apparatus of claim 1 , further comprising a protective film on the insulating film.
