Abstract

A display device according to one or more embodiments includes a display panel configured to display an image, a window substrate above the display panel, and including a display area configured to transmit the image therethrough, and a non-display area around the display area, a first adhesive layer between the display panel and the window substrate, and a decoration film above an upper surface of the window substrate. The decoration film includes a base film and a printing layer at a first surface of the base film.

First claim

What is claimed is:

1 . A display device comprising:
a display panel configured to display an image; a window substrate above the display panel, and comprising:
a display area configured to transmit the image therethrough; and
a non-display area around the display area;
a first adhesive layer between the display panel and the window substrate; and a decoration film above an upper surface of the window substrate, and comprising:
a base film; and
a printing layer at a first surface of the base film.

2 . The display device of claim 1 , wherein the window substrate comprises a plastic substrate.

3 . The display device of claim 1 , further comprising a hard coating layer at a second surface of the base film.

4 . The display device of claim 1 , further comprising a step-difference compensation layer surrounded by portions of the printing layer at a lower surface of the decoration film.

5 . The display device of claim 1 , further comprising a second adhesive layer between the window substrate and the decoration film.

6 . The display device of claim 5 , wherein the printing layer contacts the second adhesive layer.

7 . The display device of claim 1 , wherein the printing layer corresponds to the non-display area.

8 . The display device of claim 7 , further comprising an auxiliary adhesive layer at a lower surface of the printing layer.

9 . The display device of claim 8 , wherein the auxiliary adhesive layer contacts the second adhesive layer.

10 . The display device of claim 1 , wherein the printing layer comprises:
a first decor printing layer on the first surface of the base film; and a light blocking printing layer on the first decor printing layer.

11 . The display device of claim 10 , wherein the light blocking printing layer contacts the second adhesive layer.

12 . The display device of claim 10 , wherein the first decor printing layer comprises a white printing layer.

13 . The display device of claim 10 , wherein the light blocking printing layer comprises a black printing layer.

14 . The display device of claim 10 , wherein the printing layer further comprises a second decor printing layer between the light blocking printing layer and the first decor printing layer.

15 . The display device of claim 14 , wherein the second decor printing layer comprises a pearl pigment and has a transparent color.

16 . The display device of claim 1 , wherein the display panel comprises:
a first substrate; a capping layer on the first substrate; and a thin film encapsulation layer on the capping layer.

17 . The display device of claim 16 , further comprising a polarizer on the thin film encapsulation layer and facing the window substrate.

18 . The display device of claim 17 , wherein the first adhesive layer is between the polarizer and the window panel.

19 . The display device of claim 17 , further comprising a touch screen panel on the polarizer.

20 . The display device of claim 16 , wherein the display panel comprises an organic light emitting diode (OLED) display panel.
