Abstract: A display device includes a substrate including a plurality of sub-pixels, a first buffer layer on the substrate, an etch stopper on the first buffer layer, a second buffer layer covering the first buffer layer, and a first transistor on the second buffer layer. The first transistor includes a source electrode and a drain electrode overlapping the etch stopper. The etch stopper includes a hole in which at least one of the source electrode and the drain electrode is disposed. The etch stopper is spaced apart from the source electrode and the drain electrode. Therefore, it is possible to prevent moisture and impurities from penetrating into a display device by protecting a buffer layer.

Abstract: An image sensing device is provided to include a plurality of unit pixel regions arranged in a first direction and a second direction, a first device isolation region structured to isolate the plurality of unit pixel regions from each other, a plurality of photoelectric conversion regions in the substrate to form a plurality of imaging pixels structured to generate photocharges, a plurality of second device isolation regions configured to define active regions of the plurality of imaging pixels, a plurality of floating diffusion regions formed in a first active region to store the photocharges, and a plurality of transfer gates structured to transmit the photocharges. The floating diffusion region is located contiguous to the transfer gate in the first direction and the second direction and is structured to surround a plurality of side surfaces of a corresponding transfer gate.
