Abstract: Provided is a display device comprising a substrate, a first data line and a second data line disposed on the substrate and extended in a first direction, an anode electrode disposed on the first data line and the second data line, a pixel-defining film disposed over the anode electrode and defining an emission area, an organic light-emitting layer disposed on the anode electrode, and a cathode electrode disposed on the organic light-emitting layer, wherein each of the first data line and the second data line has a curved shape when viewed from a top where the first anode electrode and the second anode electrode overlap the anode electrode.

Abstract: A display device includes a light emitting element including a pixel electrode, a light emitting layer, and a common electrode. A capping layer is disposed on the common electrode. An auxiliary layer is disposed on the capping layer. A thin film encapsulation layer includes a first encapsulation layer, a second encapsulation layer, and a third encapsulation layer. The first encapsulation layer includes a first inorganic insulating layer including silicon nitride; a second inorganic insulating layer including silicon oxide; and a third inorganic insulating layer including silicon oxynitride. The auxiliary layer has a thickness of 200 ? to 1400 ?, the first inorganic insulating layer has a thickness of 400 ? to 3500 ?, the second inorganic insulating layer has a thickness of 200 ? to 2400 ?, and the third inorganic insulating layer has a thickness of 4000 ? or more.

Abstract: Provided herein is a fish robot. The fish robot includes a head unit corresponding to head portion of a fish; a driving unit coupled to the head unit to generate driving force by sinusoidal swimming movement; a waterproof cover coupled to the head unit with elasticity in which the driving unit being inserted to be sealed; and a body unit coupled to the head unit with elasticity corresponding to body portion of the fish in which the waterproof cover being inserted to be supported.

Abstract: A multi-joint fish robot capable of rapid acceleration propulsion, including: a main body segmented into a first body, a second body and a third body; joints connecting the respective bodies; and a caudal fin provided at an end portion of a third body, and swims forming a curve by operations of the joints. The fish robot has a first occupancy ratio of a length of the caudal fin to a full length of the fish robot with respect to a swimming direction, in which the fish robot swims, and the first occupancy ratio ranges from 0.15 to 0.35, or the fish robot has a second occupancy ratio of a length of the first body to a length of the main body excluding the caudal fin with respect to a swimming direction, in which the fish robot swims, and the first occupancy ratio ranges from 0.45 to 0.75.
