ABSTRACT:
A reflective type display apparatus having a plurality of pixels includes: a first substrate; a second substrate provided in parallel to the first substrate, the second substrate being transparent to external light; a plurality of transparent pixel electrodes formed on the first substrate; a transparent counter electrode layer formed on the second substrate; a light modulating layer for modulating the external light in accordance with voltages between the plurality of transparent pixel electrodes and the transparent counter electrode, the light modulating layer being interposed between the plurality of transparent pixel electrodes and the transparent counter electrode; wherein a light scattering layer in which fine particles are dispersed in a matrix is interposed between the plurality of transparent pixel electrodes and the first substrate, the light scattering layer scatters the external light.
