A display device and a method of driving the same, in which the display device includes: a light-emitting element; a first capacitor connected between first and second contact points; a driving transistor that has a control terminal connected to the second contact point, an input terminal connected to a driving voltage, and an output terminal connected to the light-emitting element; a first switching transistor connected between a data voltage or a sustain voltage and the first contact point; a second switching transistor connected between the second contact point and the output terminal of the driving transistor; and a third switching transistor connected between a reference current source and the output terminal of the driving transistor.

Display device and method of driving the same

Laser crystallization equipment includes a laser generator generating a laser beam, the laser beam being directed toward a processing target substrate, and a blade member over the processing target substrate, the blade member being configured to chop the laser beam with a predetermined width in two directions, wherein two ends of the laser beam chopped by the blade member are irradiated to the processing target substrate as diffraction light.

A mask for sequential lateral solidification (SLS) which is capable of preventing an overlapping region and a diagonal stain based on a crystallization pattern of an active layer. The mask for SLS, which moves in a first direction and selectively transmits a laser beam emitted by a laser emitting device, includes slits which are formed such that the width of a slit in the first direction is smaller than the width of the slit in a second direction, which is perpendicular to the first direction. Each of the slits is tilted by a predetermined angle with respect to the first direction.
