Abstract: A method for manufacturing a light emitting element includes forming a first semiconductor structure including a first semiconductor layer doped with a first conductivity type dopant disposed on a base substrate, a light emitting layer disposed on the first semiconductor layer, and a second semiconductor layer disposed on the light emitting layer and doped with a second conductivity type dopant; forming a second semiconductor structure spaced apart from another second semiconductor structure on the base substrate by etching the first semiconductor structure in a direction perpendicular to a surface of the base substrate; and activating a second conductivity type dopant in the second semiconductor layer of the second semiconductor structure to form a light emitting element core.

Abstract: A display device including pixels; a data driver configured to apply a data signal to data lines connected to the pixels; and a signal controller configured to receive an image signal, a data enable signal, and a main clock signal, and to transmit an image data signal and an output signal that instructs transmitting of the data signal to the data driver. The signal controller is configured to detect electrostatic discharge (ESD) noise using the main clock signal and to mask the output signal when the image signal is distorted as a result of the ESD noise.

Abstract: A light emitting element includes a first semiconductor layer; an emission layer disposed on the first semiconductor layer; a second semiconductor layer disposed on the emission layer; an electrode layer disposed on the second semiconductor layer; and an insulating film surrounding side surfaces of the first semiconductor layer, the emission layer, and the second semiconductor layer and surrounding a portion of the electrode layer at an end portion of the light emitting element on which the electrode layer is disposed. The electrode layer includes a first surface adjacent to the second semiconductor layer; a second surface facing the first surface and having a width less than a width of the first surface; and a side surface that connects the first surface and the second surface and has a slope in a range of about 75° to about 90° with respect to the first surface of the electrode layer.
