Abstract

A display panel includes a first substrate defining a display area thereof in which an image is displayed and a pad area thereof which is disposed extended from an edge of the display area and in which the image is not displayed; a second substrate disposed overlapping the display area of the first substrate; a spacer disposed on the pad area of the first substrate; and an upper polarizing plate disposed on the second substrate, the upper polarizing plate extended further than the second substrate to be disposed on the spacer on the pad area of the first substrate The spacer includes a body portion and a light-blocking layer which is disposed on a surface of the body portion.

First claim

What is claimed is:

1 . A display panel comprising:
a first substrate defining a display area and a pad area; a second substrate disposed on the display area of the first substrate; a polarizing member disposed on the second substrate, the polarizing member extended further than the second substrate to be disposed on the pad area of the first substrate; and a spacer disposed between the polarizing member and the pad area of the first substrate.

2 . The display panel of claim 1 , wherein the spacer comprises a flexible material.

3 . The display panel of claim 1 , wherein the spacer comprises a polymer resin.

4 . The display panel of claim 1 , wherein the spacer comprises a body portion and a printing layer which is disposed on a surface of the body portion.

5 . The display panel of claim 4 , wherein the printing layer is disposed between the first substrate and the body portion.

6 . The display panel of claim 4 , wherein the printing layer is disposed between the body portion and the polarizing member.

7 . The display panel of claim 4 , wherein the printing layer is a light-blocking layer.

8 . The display panel of claim 1 , wherein the spacer is attached to the polarizing member.

9 . The display panel of claim 1 , further comprising a flexible printed circuit board which is disposed between the spacer and the pad area and attached to the pad area.

10 . The display panel of claim 1 , wherein
a curved area having a first curved surface is further defined in the first substrate, the polarizing member and the spacer extend to a region overlapping the curved area in a plan view, and the spacer has a second curved surface corresponding to the first curved surface.

11 . The display panel of claim 10 , wherein the display area of the first substrate and the pad area of the first substrate are flat.

12 . The display panel of claim 10 , wherein
the curved area extends from the pad area, and the pad area is defined between the display area and the curved area.

13 . A display panel comprising:
a first substrate defining a display area and a pad area; an organic member disposed on the pad area of the first substrate; a second substrate disposed on the display area of the first substrate; and an optical film disposed on the second substrate and the organic member.

14 . The display panel of claim 13 , further comprising a printing layer disposed on one surface of the organic member facing the pad area.

15 . The display panel of claim 13 , further comprising a printing layer disposed on one surface of the organic member facing the optical film.

16 . The display panel of claim 13 , wherein the optical film is a polarizing member.

17 . A display panel comprising:
a first substrate defining a display area and a pad area; a filler member disposed on the pad area of the first substrate; a second substrate disposed on the display area of the first substrate; and an optical film disposed on the second substrate and the filler member.
