Abstract: The present invention relates to a heteroaryl derivative compound and a use thereof. Since the heteroaryl derivative of the present invention exhibits excellent inhibitory activity against EGFR, the heteroaryl derivative can be usefully used as a therapeutic agent for EGFR-associated diseases.

Abstract: Embodiments of the disclosure concern display devices. The voltage line for supplying driving voltage to the cathode electrode of the light emitting element in the subpixel and the voltage line for supplying voltage for initializing the subpixel are integrated together. This allows for use of fewer voltage lines in the active area, along with easier arrangement of the voltage lines. The wire resistance may be reduced by adjusting the width of the voltage lines. The reduction in wire resistance may decrease brightness deviation or increase the aperture ratio or transmittance of the subpixel, thus allowing the display device higher light emission efficiency or transmittance.

Abstract: Proposed is an apparatus for checking a golf divot, which checks a position where a golf club comes into contact with the ground, a ground contact area, or a trace of the golf club when a user hits a golf ball with a golf club, so as to enable improvement of the user's swing, the apparatus including: a ball resting plate body having multiple pin-holes formed therethrough; multiple pins which are inserted into the pin-holes of the ball resting plate body, respectively, to vertically move and installed to allow upper end portions thereof to protrude upward from the ball resting plate body; and a ball resting plate body support means which supports the ball resting plate body in a state where the ball resting plate body is spaced a predetermined height apart from the ground.

Abstract: There is provided an organic thin film transistor and a method of manufacturing the same. The organic thin film transistor includes: an insulating substrate on which a plurality of barrier ribs and a plurality of grooves partitioned by the barrier ribs are formed; source and drain electrodes each formed on the grooves spaced apart from each other among the plurality of grooves; a gate electrode formed on the groove between the source and drain electrodes; an opening formed by etching the barrier ribs between the source electrode and the gate electrode and between the gate electrode and the drain electrode; a gate insulating film formed on the opening; and an organic semiconductor layer formed on the gate insulating film. The organic thin film transistor is capable of mass production and has excellent electrical characteristics.
