US Patent 7423711 Display apparatus

A display apparatus includes first and second oppositely disposed substrates, at least one of which is a transparent substrate, a display layer, disposed between the first and second substrates, for being placed in an optical state switchable between a light transmission state and a light interruption state, for each of a plurality of pixel units, and a reflection surface provided on the first substrate. A scattering layer is disposed on the second substrate opposite to the first substrate, and a structure is disposed at a boundary portion between adjacent pixels on the first substrate. The structure is a light absorption structure absorbing not less than 60% of incident light.
