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: a pixel part partitioned into blocks; a scale factor provider which calculates a first load value of input image data for the pixel part, calculates a second load value of the input image data for each block, and generates a scale factor based on the first and second load values; and a timing controller which generates image data by scaling gray values of the input image data based on the scale factor. The scale factor provider generates a first scale factor for commonly controlling the gray values for the blocks based on the first load value, when the first load value is greater than or equal to a reference load value, and generates a second scale factor for controlling gray value for each block based on the first and second load values, when the first load value is less than the reference load value.
