    Abstract: A display device includes a first substrate, thin film transistors, a color filter layer, a light blocking pattern, a second substrate, pixel electrodes, and, a plurality of first spacers. The first substrate includes a display area having a plurality of pixel areas and a non-display area surrounding at least part of the display area, the display area including an interior area and at least one peripheral area disposed exteriorly of the interior area. The second substrate defines with the first substrate a space to contain light transmittance material. The plurality of first spacers is disposed in the light transmittance space between the first and second substrates and only in the interior area of the display area.

    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.
