Abstract: A display device includes a first substrate, a second substrate opposite to the first substrate, a liquid crystal layer between the first substrate and the second substrate, and a plurality of spacers maintaining a cell gap between the first substrate and the second substrate. Each of the plurality of spacers includes a spacer body portion protruding from the first substrate, and a spacer pattern portion including a plurality of pillar portions protruding from the spacer body portion and a plurality of contact portions respectively on top ends of the plurality of pillar portions so as to be in contact with a bottom surface of the second substrate.

Abstract: Provided is a liquid crystal display apparatus. The liquid crystal display apparatus includes: a first substrate; a second substrate facing the first substrate; a liquid crystal layer disposed between the first substrate and the second substrate; a first liquid crystal alignment layer disposed between the first substrate and the liquid crystal layer; and a second liquid crystal alignment layer disposed between the second substrate and the liquid crystal layer. The first liquid crystal alignment layer may include a first ion adsorbing group, and the second liquid crystal alignment layer may include a second ion adsorbing group. A content of the first ion adsorbing group in the first liquid crystal alignment layer may be different from that of the second ion adsorbing group in the second liquid crystal alignment layer, or a chemical structure of the first ion adsorbing group may be different from that of the second ion adsorbing group.

Abstract: A touch sensing unit includes a touch sensor, a sensor line, a piezoelectric area, and a touch sensor controller. The touch sensor is arranged in an island shape. The sensor line is connected to the touch sensor. The piezoelectric area overlaps the touch sensor and is arranged in an island shape. The touch sensor controller receives a voltage from the piezoelectric area when the piezoelectric area receives pressure and determines a magnitude of the pressure based on the voltage.
