Abstract: An organic light-emitting display apparatus includes a pixel-defining layer configured to surround a plurality of pixels while exposing an emission area of the plurality of pixels on a substrate; and a spacer provided on the pixel-defining layer and configured to allow a mask to be placed on the spacer, the mask being arranged for deposition of an emission layer in the emission area, wherein a distance in a plane direction between the spacer and each of the plurality of pixels is within 1 μm. A color mixture between pixels may be prevented by suppressing the shadow phenomenon in deposition of an emission layer such that performance and reliability of the organic light-emitting display apparatus may be significantly improved.

Abstract: A thin film transistor array substrate includes: a first conductive layer including first lines for transmitting data signals to the thin film transistors; a second conductive layer disposed on the first conductive layer and including second lines for supplying a driving voltage to the thin film transistors; a first insulating layer disposed between a semiconductor layer and the first conductive layer and including a first material layer; a second insulating layer disposed between the first conductive layer and the second conductive layer and including a second material layer having a dielectric constant greater than that of the first material layer; and a contact plug penetrating the second insulating layer and the first insulating layer, and connecting the second conductive layer to the semiconductor layer. A taper angle of the contact plug in the second material layer is greater than that of the contact plug in the first material layer.

Abstract: A semiconductor device including a semiconductor layer, a first electrode, and a second electrode. The semiconductor layer includes a first source region, a first drain region, a second source region, and a second drain region connected to a channel region. The first gate electrode is disposed below the semiconductor layer. The first gate electrode is insulated from the semiconductor layer. The first gate electrode at least partially overlaps the shared channel region. The second gate electrode is disposed above the semiconductor layer. The second gate electrode is insulated by a second gate insulating layer. The second gate electrode at least partially overlaps the channel region.
