Drive ic and display device having the same

Abstract

In a drive IC and a display device having the same, the drive IC includes a plurality of bumps disposed on a lower surface of the drive IC and aligned in a plurality of rows along an edge of the drive IC. The bumps aligned in different rows from each other are juxtaposed in a direction perpendicular to a direction in which the bumps are aligned. Accordingly, when the drive IC is mounted on a display panel using an anisotropic conductive film, the anisotropic conductive film may be smoothly flowed through a space defined by the bumps of the drive IC, thereby improving electric properties of the drive IC and display device.
