Abstract: A liquid crystal display device includes first and second substrates opposite to each other, a liquid crystal layer between the first and second substrates, a first electrode on the first substrate in a planar shape, and a second electrode on the first substrate and including pixel electrodes, which overlap the first electrode. Each of the pixel electrodes includes minute branches disposed parallel to one another, and connecting branches, which connect the minute branches, the minute branches include an edge area defined on a side thereof, and a main area defined by a remaining area, the connecting branches are disposed alternately on outer sides of the edge and main areas, and a first angle formed by the minute branches in the edge area with respect to a first direction is larger than a second angle formed by the minute branches in the main area with respect to the first direction.

Abstract: A display device includes: a substrate; a display area including pixels arranged on the substrate; a first area disposed at one side of the display area; a second area including pads arranged on the substrate; a bending area disposed between the first area and the second area; and a fan-out line disposed in the first area, the bending area, and the second area. The fan-out line includes: a plurality of sub-routing lines arranged in the first area and electrically connected to each other; and a plurality of sub-pad lines arranged in the second area and electrically connected to each other. The number of the plurality of sub-routing lines is greater than the number of the plurality of sub-pad lines.

Abstract: A display device includes a substrate on which an active region and a non-active region disposed are defined. The non-active region at least partially surrounds the active region. A light-emitting element is disposed in the active region on the substrate. An encapsulation layer is disposed on the light-emitting element. Block patterns are disposed in the non-active region on the substrate and at least partially surround the active region. The non-active region includes a first non-active region positioned at a first side of the active region and a second non-active region positioned at a second side of the active region. There are more block patterns disposed in the first non-active region than in the second non-active region.

Abstract: A display device may include: pixels coupled to first scan lines, second scan lines, emission control lines, and data lines; a first scan driver to supply a first scan signal to the first scan lines in a first period and a second period; a second scan driver to supply a second scan signal to the second scan lines in the first period without supplying the second scan signal to the second scan lines in the second period; an emission driver to supply an emission control signal to the emission control lines in the first period and the second period; a data driver configured to supply data signals to the data lines in the first period without supplying the second scan signal to the second scan lines in the second period; and a power supply to supply a first initialization power source to the pixels through a first initialization and to supply a second initialization power source to the pixels through a second power line.
