Display device and method of manufacturing the same
A display device includes: a display panel and a circuit board. The circuit board includes a base layer, a circuit pattern disposed on the base layer and electrically connected to the display panel, an alignment pattern disposed on the base layer and including the same material as the circuit pattern, a first cover layer disposed on the base layer, covering the circuit pattern, and provided with a first opening defined therethrough to expose the alignment pattern, and a second cover layer disposed on the first cover layer, provided with a second opening defined therethrough and overlapping the first opening, and including a barcode pattern defined on a surface of the second cover layer opposite to the first cover layer. The first cover layer overlapping the second opening is exposed through the second opening without being covered by the second cover layer.
1 . A display device comprising:
a display panel; and
a circuit board connected to the display panel, the circuit board comprising:
a base layer;
a circuit pattern disposed on the base layer and electrically connected to the display panel;
an alignment pattern disposed on the base layer and comprising a same material as the circuit pattern;
a first cover layer disposed on the base layer, covering the circuit pattern, and provided with a first opening defined therethrough to expose the alignment pattern; and
a second cover layer disposed on the first cover layer, provided with a second opening defined therethrough and overlapping the first opening, and comprising a barcode pattern defined on a surface of the second cover layer opposite to the first cover layer,
wherein the first cover layer overlapping the second opening is exposed through the second opening without being covered by the second cover layer.
2 . The display device of claim 1 , wherein the alignment pattern is spaced apart from the first cover layer, and a part of the base layer overlapping the first opening is exposed through the first opening without being covered by the first cover layer.
3 . The display device of claim 1 , wherein the alignment pattern has a brightness different from a brightness of the base layer.
4 . The display device of claim 1 , wherein an inner side surface of the first cover layer, which defines the first opening, surrounds the alignment pattern.
5 . The display device of claim 1 , wherein the alignment pattern has at least one of a circular shape and a polygonal shape in a plan view, and the polygonal shape comprises a first side and a second side perpendicular to the first side.
6 . The display device of claim 1 , wherein the alignment pattern is provided in plural, the alignment patterns comprise a first pattern extending in a first direction and a second pattern extending in a second direction crossing the first direction and spaced apart from the first pattern, at least a portion of the first pattern overlaps the barcode pattern in the second direction, and at least a portion of the second pattern overlaps the barcode pattern in the first direction.
7 . The display device of claim 6 , wherein each of the first opening and the second opening is provided in plural, the first openings comprise a first sub-opening through which the first pattern is exposed and a second sub-opening through which the second pattern is exposed, and the second openings comprise a third sub-opening overlapping the first sub-opening and a fourth sub-opening overlapping the second sub-opening.
8 . The display device of claim 1 , wherein each of the first opening and the second opening has one of a quadrangular shape, a pentagon shape, and a circular shape in a plan view.
9 . The display device of claim 1 , wherein each of the circuit pattern and the alignment pattern comprises a metal material.
10 . The display device of claim 1 , wherein the first cover layer comprises an organic insulating material.
11 . The display device of claim 1 , wherein the second cover layer comprises:
a shielding layer disposed on the first cover layer and comprising a metal material; and
an insulating layer disposed on the shielding layer and comprising an organic insulating material.
12 . The display device of claim 11 , wherein the barcode pattern is defined by a portion of the insulating layer, which is exposed by removing at least a portion of the insulating layer.
