A display device includes a plurality of color filters that is disposed on a first base substrate and in pixel regions arranged in a matrix shape, a plurality of driving electrodes that is disposed on the color filters, a plurality of transistors that is provided on the first base substrate and in a non-pixel region between adjacent pixel regions in a second direction and is connected to the driving electrodes, a plurality of blocking column spacers that is provided below a second base substrate and in the non-pixel region between the adjacent pixel regions in the second direction and extending in a first direction, and a plurality of dummy color filters that is provided in a single-layered structure on the transistors. The dummy color filters that has a less number than that of the transistors support the blocking column spacers.

Display device

A curved display device includes a curved first substrate, a curved second substrate, a liquid crystal layer, a first alignment layer, and a second alignment layer. The second substrate faces the first substrate. The liquid crystal layer is interposed between the first and second substrates and includes liquid crystal molecules. The first alignment layer includes reactive mesogens polymerized to each other and is disposed between the first substrate and the liquid crystal layer. The second alignment layer is disposed between the second substrate and the liquid crystal layer. Among the liquid crystal molecules, first liquid crystal molecules disposed in the vicinity of the first alignment layer have a first pretilt angle, and second liquid crystal molecules disposed in the vicinity of the second alignment layer have a second pretilt angle different from the first pretilt angle.

Curved display device including alignment layer and method of manufacturing the same

A curved display device includes a display substrate, an opposite substrate, and a liquid crystal layer interposed between the display substrate and the opposite substrate. The display substrate is curved along a first direction and includes a pixel electrode and a second alignment layer disposed on the pixel electrode. The opposite substrate is coupled to the display substrate to be curved along the first direction and includes a common electrode and a first alignment layer disposed on the common electrode. The first alignment layer comprises different material from the second alignment layer. The pixel electrode includes branch portions extending in a direction inclined with respect to the first direction when viewed in a plan view, and a pitch, which is defined by a sum of a width of each branch portion and a distance between the branch portions, is within a range from about 7.5 micrometers to about 8.5 micrometers.
