摘要：
Provided herein is an image display apparatus for displaying high resolution images by shifting pixels based on wobbling operation by placing a TN cell consisting of a polarization changing liquid crystal plate and a birefringence plate on the front side of an LCD to be driven by video signals, the image display apparatus being provided with a correction circuit to which video signal of the preceding filed stored to a field memory, video signal of the current field and a field discriminant signal are inputted, the LCD being driven by correction video signals generated at the correction circuit so as to display a high resolution image mitigating degradation in image quality due to response delays of the LCD and TN cell.
