Abstract: The present invention relates to a liquid crystal display device, and more particularly, to a gate-in-panel (GIP) type dual gate structure liquid crystal display device for minimizing a region occupied by a gate driving unit in the GIP structure liquid crystal display device in which the gate driving unit supplying a gate driving signal is formed on a liquid crystal panel to implement a narrow-bezel, and improving image quality deterioration due to signal delay. According to the present invention, the number of stages may be reduced through the structure of alternately outputting a gate driving voltage other than the structure of simultaneously outputting a gate driving voltage from two gate driving units in a dual GIP type liquid crystal display, thereby minimizing an area occupied by the gate driving unit.

Abstract: An organic light emitting diode (OLED) includes a first emitting material layer disposed adjacently to a first electrode and a second emitting material layer disposed adjacently to a second electrode. The first emitting material layer includes a first compound having high affinity to holes and a second compound of thermally activated delayed fluorescent material, and the second emitting material layer includes a fourth compound having high affinity to electrons and implementing triplet-triplet annihilation. Two emitting material layers having adjusted energy levels allow the OLED to lower its driving voltages and improve its luminous efficiency and luminous lifetime.
