An optical film in which a function of a brightness enhancement film is maintained and variations in brightness and chromaticity within a film plane are suppressed is provided. The controller also receives a measured torque of the transmission at the particular value of the transmission parameter, and outputs a modified torque estimate for the particular value of the transmission parameter based on the measured torque. The stage includes a mask on which the first electron beam is radiated. The active component is electrically connected with the corresponding scan line and the corresponding data line, the DDE being electrically connected with the corresponding control line, the pixel electrode being electrically connected with the active component.
