Abstract: Blue bright spots occurring when using overhead projectors with liquid crystal modules (LCDs) are prevented by providing intercepting filter in the liquid crystal module for modifying light reaching the thin film transistors of the LCDs in the portion of the spectrum absorbed by and passing through the protection layer formed on the TFT. In the case where protection layer on the TFT is formed of an amorphous silicon layer, the intercepting filter has the characteristic of modifying the light having wavelengths of 380 nm to 500 nm. The intercepting filter being a color filter of other than blue is formed just above the TFT at least part of which is related to a cell of blue.
