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.

Abstract: A display panel includes a first display substrate including a display area and a non-display area which is at a periphery of the display area, a second display substrate facing the first display substrate, a display device in the display area between the first and second display substrates and including a first electrode, an optical layer including an optical layer material, and a second electrode, and a sealing member which is disposed in the non-display area and attaches the first and second display substrates to each other. The sealing member defines a sealing portion thereof which restricts movement of the display area optical layer material to outside the display area, and a receiving portion thereof in which the optical layer material is receivable.
