Abstract: A flexible circuit film including a first flexible film, a second flexible film facing the first flexible film, and a plurality of wirings arranged between the first flexible film and the second flexible film. The wirings have different widths and bend in different directions, and a guide film including a material more rigid than the first and second flexible films is arranged on ends of the first flexible film. The guide film includes a tear-preventing portion overlapping with a bending portion of a shortest one of the wirings while covering portions of an inner edge near inner corners of a U-shaped flexible circuit film.

Abstract: A display device includes gate lines, data lines, pixels, a gate driver, a data driver, and a timing controller. The gate lines extend in a first direction. The data lines extend in a second direction crossing the first direction. Each of the pixels is connected to a corresponding gate line of the gate lines and a corresponding data line of the data lines. The gate driver is configured to drive the gate lines. The data driver is configured to drive each data line of the data lines in response to a corresponding data signal. The timing controller is configured to, in response to an image signal and a control signal, apply the corresponding data signals to the data driver and control the gate driver. Each corresponding data signal reflects a kickback compensation value corresponding to a distance between the gate driver and the corresponding data line in the first direction.
