Abstract
A circuit film comprises a first circuit formed on a film substrate for outputting a driving signal to a display device, and a plurality of input lines formed on the film substrate. The display device includes a display panel which has first and second signal lines, a second-circuit film which has a second circuit for outputting a driving signal to the second signal line, and a control board for controlling the first and second circuits. The plurality of input lines include a first input line for inputting a control signal to the first circuit and a second input line for inputting a control signal to the second circuit. The film substrate is connected to the control board and the display panel such that a driving signal is input from the control board to the first and second circuits through the first and second input lines, respectively.
