Abstract
An electroluminescence display device and manufacturing method thereof are provided. An electroluminescence display device includes a pixel, having: an electroluminescence diode, a driving transistor configured to supply a current to the electroluminescence diode, and a switching transistor configured to switch a signal supplied to the driving transistor, wherein a size of a channel area of the driving transistor is different from a size of a channel area of the switching transistor, and wherein a taper angle deviation of the channel areas of the driving transistor and the switching transistor is less than or equal to 10°.
