Abstract
A display device includes: a first substrate; a second substrate overlapping the first substrate; a common electrode disposed on the second substrate; a column spacer disposed between the pixel electrode and the common electrode; and a plurality of pixels. Each of the plurality of pixels includes a transistor disposed on the first substrate and a pixel electrode electrically connected to the transistor through a hole. The display device further includes a plurality of column spacers disposed between the pixel electrode and the common electrode. The plurality of column spacers include a main spacer having a first height and a sub-spacer having a second height that is different from the first height. At least one of the main spacer and the sub-spacer includes a first spacer having a first planar area and a second planar spacer having a second planar area that is different from the first planar area.
