摘要：
A liquid crystal device comprises a pair of substrates and a ferroelectric liquid crystal disposed between the substrates. At least one of the substrates has thereon a color filter layer and a protection layer for preventing direct contact between the color filter and the ferroelectric liquid crystal. Particulate spacers are preferably disposed between the substrates. The protection layer preferably comprises a film having a pencil hardness of HB or harder (JIS K 5401).
