    Abstract: A curved liquid crystal display including a first curved substrate; a second curved substrate; a liquid crystal layer including liquid crystal molecules having negative dielectric anisotropy, the liquid crystal layer being interposed between the first and second curved substrates; a first curved liquid crystal alignment layer interposed between the liquid crystal layer and the first curved substrate; and a second curved liquid crystal alignment layer interposed between the liquid crystal layer and the second curved substrate. The second curved liquid crystal alignment layer has an average value of surface roughness values greater than an average value of surface roughness values of the first curved liquid crystal alignment layer.

    Abstract: An emissive display device includes a polycrystalline semiconductor including a channel, source region, and drain region of a driving transistor disposed on a substrate. The device includes a gate electrode of the driving transistor overlapping the channel of the driving transistor, an oxide semiconductor including a channel, a source region, and a drain region of a second transistor disposed on the substrate, and a first connection electrode. The first connection electrode includes a first connector electrically connected to the gate electrode of the driving transistor, a second connector electrically connected to a second electrode of the second transistor, and a main body disposed between the first connector and the second connector. The device includes an initialization voltage line disposed on the substrate and applying an initialization voltage. The initialization voltage line surrounds at least a part of the second connector of the first connection electrode.

    Abstract: A touch member includes a first touch electrode including a plurality of first sub-detection electrode patterns. The touch member includes a second touch electrode including a plurality of second sub-detection electrode. An electrode pattern connecting portion electrically connects adjacent second sub-detection electrode patterns. An island electrode pattern is disposed in the second touch electrode. A bridge pattern electrically connects a first sub-detection electrode of the first sub-detection electrode patterns to the island electrode pattern. The bridge pattern is formed of a first conductive layer. The first sub-detection electrode patterns, the electrode pattern connecting portion, the second sub-detection electrode patterns, and the island electrode pattern are formed of a second conductive layer. An insulating pattern is disposed between the bridge pattern and a part of the second conductive layer overlapping with the bridge pattern. The insulating pattern does not overlap a part of the bridge pattern.
