Display device and manufacturing method thereof
View Patent ↗A display device includes a first display panel, a second display panel facing the first display panel, and a plurality of spacers maintaining a distance between the first display panel and the second display panel. Each of the spacers includes column spacers, ball spacers, and an adhesive.
1. A display device comprising:
a first display panel;
a second display panel facing the first display panel; and
a plurality of cell gap spacers maintaining a distance between the first display panel and the second display panel,
wherein each of the cell gap spacers comprises column spacers, ball spacers, and an adhesive,
wherein the ball spacers and the adhesive are filled within spaces between the column spacers and enclose external walls of the column spacers.
2. The display device of claim 1 , wherein the second display panel comprises:
a flexible substrate;
a light blocking member formed on the flexible substrate;
a color filter formed on the flexible substrate; and
a common electrode formed on the color filter.
3. The display device of claim 2 , wherein the cell gap spacers are formed at portions of the second display panel so as to overlap the light blocking member.
4. The display device of claim 2 , wherein the flexible substrate includes plastic.
5. The display device of claim 2 , wherein the second display panel further comprises an alignment layer formed on the common electrode, the cell gap spacers formed on the alignment layer.
6. The display device of claim 1 , further comprising:
a liquid crystal layer interposed between the first display panel and the second display panel; and
a sealant formed between the first display panel and the second display panel and sealing the liquid crystal layer,
wherein the sealant comprises a column spacer, a ball spacer, and an adhesive.
7. The display device of claim 1 , wherein the column spacers of at least one cell gap spacer are formed on apexes and a center portion of a corresponding portion of a light blocking member of the second display panel, or on apexes of the corresponding portion, or in a triangular shape within the corresponding portion.
8. The display device of claim 1 , wherein the column spacers of at least one cell gap spacer are formed in a 3×2 matrix or a combined shape of a Y-shaped character and a reverse Y-shaped character in a corresponding portion of a light blocking member of the second display panel.
9. The display device of claim 1 , wherein the column spacers of at least one cell gap spacer have a longitudinal shape, respectively, and are disposed in a line.
10. The display device of claim 1 , wherein each cell gap spacer is formed on the second display panel to correspond to an area of the first display panel that does not transmit light, the area including at least one of a thin film transistor, a gate line, and a data line.
11. The display device of claim 1 , wherein at least one of the cell gap spacers is formed within a quadrangle size of about 40 μm by about 40 μm.
12. A display device comprising:
a first display panel;
a second display panel facing the first display panel; and
a plurality of cell gap spacers maintaining a distance between the first display panel and the second display panel,
wherein each of the cell gap spacers comprises at least one column spacer, a ball spacer, and an adhesive,
wherein the at least one column spacer, the ball spacer and the adhesive are disposed between the first display panel and the second display panel, and the adhesive contacts both the at least one column spacer and the ball spacer.
13. The display device of claim 12 , wherein the second display panel comprises:
a flexible substrate;
a light blocking member formed on the flexible substrate;
a color filter formed on the flexible substrate; and
a common electrode formed on the color filter.
14. The display device of claim 13 , wherein the cell gap spacer is formed at portions of the second display panel so as to overlap the light blocking member.
15. The display device of claim 13 , wherein the flexible substrate includes plastic.
16. The display device of claim 13 , wherein the second display panel further comprises an alignment layer formed on the common electrode, the cell gap spacers formed on the alignment layer.
17. The display device of claim 12 , further comprising:
a liquid crystal layer interposed between the first display panel and the second display panel; and
a sealant formed between the first display panel and the second display panel and sealing the liquid crystal layer,
wherein the sealant comprises a column spacer, a ball spacer, and an adhesive.
18. The display device of claim 12 , wherein each of the at least one column spacer is formed on apexes and a center portion of a tetragonal portion corresponding to a light blocking member of the second display panel, or only on apexes of the tetragonal portion, or only on apexes of a triangular portion corresponding to a light blocking member of the second display panel.
19. The display device of claim 12 , wherein each of the at least one column spacer has a longitudinal shape and is disposed in a line.
20. The display device of claim 12 , wherein each cell gap spacer is formed on the second display panel to correspond to an area of the first display panel that does not transmit light, the area including at least one of a thin film transistor, a gate line, and a data line.
