Abstract

A display device includes a display panel including a display area including a light blocking area and a non-display area around the display area, a base film disposed on the display panel, a light blocking layer that overlaps the light blocking area and is disposed on a surface of the base film, a first adhesive disposed between the display panel and the base film, a window disposed on the base film, and a second adhesive disposed between the window and the base film. A first hole defined in a portion of the light blocking area passes through the base film, the light blocking layer, the first adhesive, and the second adhesive.

Claims (25)

1. A display device comprising:

a display panel comprising a display area including a light blocking area and a non-display area around the display area;

a base film disposed on the display panel;

a light blocking layer which overlaps the light blocking area and is disposed on a surface of the base film;

a first adhesive disposed between the display panel and the base film;

a window disposed on the base film; and

a second adhesive disposed between the window and the base film,

wherein a first hole defined in a portion of the light blocking area passes through the base film, the light blocking layer, the first adhesive, and the second adhesive.

2. The display device of claim 1 , wherein the first adhesive has a thickness greater than a thickness of the second adhesive in a direction perpendicular to a plane of the display panel, and

the first adhesive comprises an optical clear adhesive, and the second adhesive comprises a pressure sensitive adhesive.

3. The display device of claim 1 , wherein the surface of the base film faces the display panel.

4. The display device of claim 3 , further comprising a printing layer which overlaps the non-display area and is disposed on the surface of the base film.

5. The display device of claim 1 , wherein an inner surface of the light blocking area, in which the first hole is defined, an inner surface of the base film, in which the first hole is defined, an inner surface of the light blocking layer, in which the first hole is defined, an inner surface of the first adhesive, in which the first hole is defined, and an inner surface of the second adhesive, in which the first hole is defined, are disposed on a same surface as each other.

6. The display device of claim 1 , further comprising:

an input sensing part disposed on the display panel;

a polarizing film disposed on the input sensing part; and

a first protective film disposed below the display panel,

wherein the first adhesive is disposed between the polarizing film and the base film, and the first hole passes through the input sensing part, the polarizing film, and the first protective film, and

an inner surface of the light blocking area, in which the first hole is defined, an inner surface of the input sensing part, in which the first hole is defined, an inner surface of the polarizing film, in which the first hole is defined, and an inner surface of the first protective film, in which the first hole is defined, are disposed on a same surface as each other.

7. The display device of claim 6 , further comprising a cushion layer disposed below the first protective film,

wherein a second hole which overlaps the first hole and is larger than the first hole is defined in the cushion layer.

8. The display device of claim 1 , wherein the second adhesive has a thickness greater than a thickness of the first adhesive in a direction perpendicular to a plane of the display panel, and

the first adhesive comprises a pressure sensitive adhesive, and the second adhesive comprises an optical clear adhesive.

9. The display device of claim 1 , wherein the surface of the base film faces the window.

10. The display device of claim 9 , further comprising a printing layer which overlaps the non-display area and is disposed on the surface of the base layer.
