DISPLAY DEVICE AND METHOD OF MANUFACTURING THE SAME

Abstract

A display device includes a display panel including a plurality of pixels, a printed circuit board driving the display panel, a flexible printed circuit and a driving package. The flexible printed circuit includes an input unit attached to a top surface of the printed circuit board and an output unit attached to the display panel. The driving package includes an input unit attached to the top surface of the printed circuit board and an output unit attached to the display panel. A length from a central portion of the driving package to the input unit of the driving package is larger than a length from a central portion of the flexible printed circuit to the input unit of the flexible printed circuit.
