Abstract
There is provided a reflection type liquid crystal display including (a) a first substrate, (b) a second substrate having a transparent electrode formed thereon in facing relation to the first substrate, and (c) a liquid crystal layer sandwiched between the first and second substrates, the first substrate including (a1) an insulating substrate, (a2) a switching device fabricated on the insulating substrate, (a3) at least one projection projecting towards the second substrate and formed on the insulating substrate in a line with the switching device, (a4) a first insulating film covering both the switching device and the projection therewith and having first raised and recessed portions formed in accordance with height of the switching device and the projection, and (a5) a light-reflective plate formed over the first insulating film and having second raised and recessed portions formed over the first raised and recessed portions, the switching device being in electrical connection with the light-reflective plate through a drain or source electrode thereof. The above-mentioned liquid crystal display has superior display ability and can be fabricated in simpler steps.
