Abstract

A lamination device includes: a stage including a fixing part; a pressing part disposed on the stage; a light source disposed between the stage and the pressing part, and configured to emit light in a direction of the pressing part; and a window fixing chuck overlapping the pressing part, wherein the pressing part includes: a light refraction part disposed adjacent to the light source and refracting, toward the window fixing chuck, the light that was emitted in the direction of the pressing part; and a head part disposed to at least partially surround the light refraction part, and configured to transmit the light that was refracted toward the window fixing chuck, wherein the head part includes a material different from that of the light refraction part.

Claims (25)

1 . A lamination device comprising:

a stage including a fixing part;

a pressing part disposed on the stage;

a light source disposed between the stage and the pressing part, and configured to emit light in a direction of the pressing part; and

a window fixing chuck overlapping the pressing part,

wherein the pressing part includes:

a light refraction part disposed adjacent to the light source and configured to refract the light that was emitted in the direction of the pressing part toward the window fixing chuck; and

a head part at least partially surrounding the light refraction part, and configured to transmit the light that was refracted toward the window fixing chuck, wherein the head part includes a material different from that of the light refraction part.

2 . The lamination device of claim 1 , wherein the light has a central wavelength of about 200 nm to about 400 nm.

3 . The lamination device of claim 1 , wherein the head part comprises silicone.

4 . The lamination device of claim 1 , wherein the light refraction part comprises glass.

5 . The lamination device of claim 1 , wherein the light refraction part has a flat shape, a concave lens shape, a convex lens shape, or a Fresnel lens shape.

6 . The lamination device of claim 1 , wherein the head part is a diaphragm.

7 . A lamination device comprises:

a fixing part configured to fix a guide film;

a pressing part disposed below the fixing part and the guide film;

a roller part disposed on the pressing part;

a light source disposed on the pressing part; and

a window fixing chuck overlapping the pressing part,

wherein the pressing part includes:

a light refraction part refracting light emitted from the light source toward the window fixing chuck; and

a head part at least partially surrounding the light refraction part and transmitting the refracted light.

8 . The lamination device of claim 7 , wherein the light emitted from the light source has a central wavelength of about 200 nm to about 400 nm.

9 . The lamination device of claim 7 , wherein the head part may be configured to extend into the window fixing chuck.

10 . The lamination device of claim 7 , wherein the light refraction part has a flat shape, a concave lens shape, a convex lens shape, or a Fresnel lens shape.
