A spatial light modulator includes a pair of transparent substrates disposed with a prescribed gap therebetween and each having thereon a transparent electrode, and a liquid crystal layer and a photoconductor layer disposed between the substrates, with the transparent electrode on one substrate being split into a plurality of split electrodes. A display apparatus is formed by disposing a recording medium carrying a recorded picture at different sizes between the spatial light modulator and a writing light source. Depending on the picture size to be displayed on the spatial light modulator, a number among the plurality of split electrodes are selected for writing voltage application under illumination with writing light based on picture size data recorded in the recording medium, whereby a selected size of picture is written in the spatial light modulator and displayed thereon under illumination with reading light.
