Abstract: A laser crystallization apparatus includes: a plurality of laser generators which generates an incident laser beam; an optical system which optically converts the incident laser beam to an output laser beam; a process chamber in which a thin film formed on a substrate is crystallized by the output laser beam radiated thereto; a first monitoring device which detects a synthesized pulse of the output laser beam; a second monitoring device which detects individual pulses of the incident laser beam; and a controller which controls oscillation times of the plurality of laser generators. The controller generates a plurality of synthesized pulses by combining the individual pulses of the incident laser beam, and derives an optimal synthesized pulse from the plurality of synthesized pulses.

Abstract: A display panel includes a base layer including a boundary region extending in a first direction, a first pixel region adjacent to the boundary region in a second direction, and a second pixel region spaced apart from the first pixel region with the boundary region therebetween, lower insulating layers above the base layer, and defining a valley hole corresponding to the boundary region, a first conductive pattern including a portion inside the valley hole, a first organic layer including a portion above the lower insulating layers, and a portion covering the first conductive pattern and filling the valley hole, pixel circuits respectively overlapping the first and second pixel regions, light-emitting elements above the first organic layer, respectively overlapping the first and second pixel regions, and respectively electrically connected to the pixel circuits, and a second conductive pattern above the first organic layer, and including a portion overlapping the boundary region.
