Abstract
Abstract A liquid crystal display apparatus includes: a first substrate having a silicon layer on the surface thereof; a transparent second substrate placed so as to face the silicon layer; and a liquid crystal layer sandwiched between the first substrate and the second substrate, wherein the first substrate includes a plurality of switching elements formed in the silicon layer, a protection layer formed on the surface of the first substrate so as to cover the switching elements, a plurality of pixel electrodes with gaps therebetween formed in a matrix on the protection layer, and a filler for filling the gaps, wherein the surface of the filler is formed so as to be at the same level as that of the surfaces of the pixel electrodes.
