Abstract
A method for manufacturing a display device includes preparing a circuit board including a drive circuit for driving a LED chip, forming a connecting electrode on the circuit board, forming an adhesive layer on the connecting electrode, adhering a terminal electrode of the LED chip on the adhesive layer and joining the connecting electrode and the terminal electrode by irradiating a laser light. The adhesive layer may be formed only on a upper surface of the connecting electrode.
