Display panel and method of manufacturing the same comprising a column spacer having a bottom side having a shape of a concave-sided polygon

1. A display panel comprising:

a first substrate;

a second substrate arranged opposite to the first substrate; and

a column spacer formed on at least one of the first substrate and the second substrate to maintain a space between the first and second substrates,

wherein the column spacer has a bottom side having a shape of a concave-sided polygon comprising at least two smooth concave sides connected with each other by a rounded corner between the at least two concave sides.

2. The display panel of claim 1 , wherein the concave-sided polygon has at least four corners.

3. The display panel of claim 1 , wherein a shape of a traverse section of the column spacer is a concave-sided polygon including a plurality of corners and a plurality of concave sides connecting the corners.

4. The display panel of claim 1 , wherein the column spacer is formed by exposure using a projection type of light exposer and a mask.

5. The display panel of claim 4 , wherein the exposure is performed in a state in which the mask is disposed away from a focal point of the light exposer.

6. The display panel of claim 4 , wherein an average inclination angle of the column spacer relative to a surface of the first substrate or the second substrate is about 60 degrees to about 90 degrees.

7. The display panel of claim 1 , wherein the column spacer is formed by exposure using a proximity type of light exposer and a mask.

8. The display panel of claim 7 , wherein the mask has a pattern of a polygon having at least four corners.

9. The display panel of claim 7 , wherein an average inclination angle of the column spacer relative to a surface of the first substrate or the second substrate is about 10 degrees to about 50 degrees.

10. A method of manufacturing a display panel, comprising:

forming a first substrate including thin film transistors and pixel electrodes;

forming a second substrate including light blocking members and color filters; and

forming a column spacer on at least one of the first substrate or the second substrate, the column spacer maintaining a space between the first and second substrates, the column spacer having a bottom side having a shape of a concave-sided polygon comprising at least two smooth concave sides connected with each other by a rounded corner between the at least two concave sides.

11. The method of claim 10 , wherein the concave-sided polygon is a concave-sided polygon having at least four corners.

12. The method of claim 10 , wherein a shape of a traverse section of the column spacer is a concave-sided polygon including a plurality of corners and a plurality of concave sides connecting the corners.

13. The method of claim 10 , wherein the column spacer is formed by exposure using a projection type of light exposer and a mask.

14. The method of claim 13 , wherein the exposure is performed in a state in which the mask is disposed away from the focal point of the light exposer.

15. The method of claim 13 , wherein an average inclination angle of the column spacer relative to a surface of the first substrate or the second substrate is about 60 degrees to about 90 degrees.

16. The method of claim 10 , wherein the column spacer is formed by exposure using a proximity type of light exposer and a mask.

17. The method of claim 16 , wherein the mask has a pattern of a polygon having at least four corners.

18. The method of claim 16 , wherein an average inclination angle of the column spacer relative to a surface of the first substrate or the second substrate is about 10 degrees to about 50 degrees.
