Electronic apparatus having thin film transistors

摘要

In a projector using an optical engine that is constituted of three LCDs, the active layer thickness of TFTs constituting each LCD is optimized in accordance with the wavelength of illumination light. By making the active layer thickness smaller as the wavelength becomes shorter, leak current due to stray light is suppressed and the degrees of display failures such as crosstalk can be lowered to levels that are not problematic.
