DRIVER INTEGRATED CIRCUIT CHIP, DISPLAY DEVICE HAVING THE SAME, AND METHOD OF MANUFACTURING A DRIVER INTEGRATED CIRCUIT CHIP

摘要

A driver integrated circuit chip is provided. The driver integrated circuit chip includes a base substrate including at least one driver integrated circuit, a plurality of metal lines, and a passivation layer covering the driver integrated circuit and the metal lines; a plurality of input bumps arranged near a first longer side of the base substrate; a plurality of output bumps arranged near a second longer side of the base substrate; and a plurality of dummy bumps arranged on a central region of the base substrate, the dummy bumps being arranged between the input bumps and the output bumps. Each of the dummy bumps has a stacked layer structure that is different from a stacked layer structure of each of the input bumps and the output bumps.
