Method for manufacturing image display device, image display device, and TV apparatus

An image display apparatus capable of displaying a preferable image whose dark place contrast has a large value and whose color-reproducibility and gray-level reproducibility are excellent. A voltage level of a scanning selective signal is changed in response to a request from outside or the like, so that a black level luminance is reduced to improve dark place contrast. In addition, when the voltage level of the scanning selective signal is changed, a conversion table for converting an input luminance into a modulation signal is changed to another conversion table. Therefore, for example, it is possible to maintain a display gray-level characteristic before and after the voltage level of the scanning selective signal is changed.
