Abstract
An LCD device has a distorted and/or curved shape corresponding to an image formed on the screen before correcting for distortion and/or curvature of the image formed on the screen, which are generated due to distortion aberration and/or curvature aberration of the projection lens unit, so that distortion and/or curvature can be corrected. The LCD device has a pin-cushion type structure distorted and curved positively (+) so that negative (−) distortion and curvature of the image formed on the screen, which is generated due to distortion aberration and curvature aberration of the projection lens unit, can be corrected. Also, the LCD device includes a front substrate and a rear substrate, each having electrodes formed thereon, and the front substrate and/or the rear substrate have a pin-cushion shape distorted and/or curved positively (+). Thus, distortion aberration and/or curvature aberration of optical lenses of a projection lens unit can be corrected by appropriately correcting a light emitting point of image light.
