摘要： The present invention provides a capsular micro light-emitting device and a method for manufacturing the same. The capsular micro light-emitting device includes a light emitting part having at least a light emitting layer 13 and constituting one pixel, a capsular encapsulation layer 17 for individually encapsulating the light emitting part, and first and second electrodes 11 and 15 for applying a voltage to the light emitting part. The method comprises the steps of: coating a light emitting layer material onto an outer periphery of a linear first electrode material and drying the light emitting layer material to form a tubular light emitting layer; forming a tubular second electrode layer by supplying a second electrode material onto an outer periphery of the tubular light emitting layer to obtain a tubular multilayer body; applying a laser beam onto an outer periphery of the tubular multilayer body for irradiation at prescribed intervals to form exposed portions where the first electrode material is exposed at prescribed intervals; coating an encapsulant onto the outer periphery of the tubular multilayer body formed with the exposed portions and drying the encapsulant to form an encapsulation layer; and cutting the tubular multilayer body formed with the encapsulation layer at the exposed portions to obtain the capsular micro light-emitting device comprising a light emitting part having at least a light emitting layer and constituting one pixel, a capsular encapsulation layer for individually encapsulating the light emitting part, and first and second electrodes for applying a voltage to the light emitting layer.
