Abstract

An electroluminescent display device and a method of manufacturing the same are provided. The electroluminescent display device includes a substrate having a display region and a terminal unit; a sealing substrate arranged above the substrate; and an encapsulant arranged on at least a portion of an edge of the substrate to seal at least the display region.

Claims (28)

1 . An electroluminescent display device, comprising:

a substrate comprising a display region and a terminal unit;

a sealing substrate arranged above the substrate; and

the encapsulant arranged at edge regions of the substrate and the sealing substrate and sealed with the display region.

2 . The electroluminescent display device of claim 1 , wherein the edge regions where the encapsulant is arranged are positioned to face each other.

3 . The electroluminescent display device of claim 1 , wherein an edge region of the substrate and/or the sealing substrate on which the encapsulant is formed comprises a recess.

4 . The electroluminescent display device of claim 3 , wherein the recess is discontinuous along the edge region where the encapsulant is arranged.

5 . The electroluminescent display device of claim 3 , wherein the recess is continuous along the edge region where the encapsulant is arranged.

6 . The electroluminescent display device of claim 3 , wherein a side surface of the recess is substantially perpendicular to the surface of the substrate and/or the sealing substrate.

7 . The electroluminescent display device of claim 3 , wherein the recess widens toward the surface of the substrate and/or the sealing substrate.

8 . A method of manufacturing an electroluminescent display device, comprising:

forming a display region on a mother substrate;

forming an encapsulant on a portion of a scribed region on a sealing mother substrate;

hardening the encapsulant;

sealing the mother substrate with the sealing mother substrate; and

cutting the mother substrate and the sealing mother substrate along the scribing region.

9 . The method of claim 8 , further comprising:

forming a recess in a portion of the scribing region of the mother substrate before forming the display region.

10 . The method of claim 9 , wherein the recess is continuous along a region where the encapsulant is formed on the mother substrate.

11 . The method of claim 9 , wherein the recess is discontinuous along a region where the encapsulant is formed on the mother substrate.

12 . The method of claim 9 , wherein a side surface of the recess is substantially perpendicular to a surface of the mother substrate and/or the mother sealing substrate.

13 . The method of claim 9 , wherein the recess widens toward a surface of the mother substrate.

14 . The method of claim 8 , further comprising:

forming a recess at a portion of the scribing region of the sealing mother substrate before forming the encapsulant.

15 . The method of claim 14 , wherein the recess is continuous along a region where the encapsulant is formed on the sealing mother substrate.

16 . The method of claim 14 , wherein the recess is discontinuous along a region where the encapsulant is formed on the sealing mother substrate.

17 . The method of claim 14 , wherein a side surface of the recess is substantially perpendicular to a surface of the mother substrate and/or the mother sealing substrate.

18 . The method of claim 14 , wherein the recess widens toward the surface of the sealing mother substrate.
