Abstract
A liquid crystal display device comprises a first substrate which has a plurality of picture element electrodes arranged in a matrix and a plurality of switching elements associated with the respective picture element electrodes to drive the electrodes, a second substrate which is opposed to the first substrate, and a liquid crystal layer provided between the first and second substrates. A micro-lens is formed between the first substrate and each picture element electrode, by which a high contrast ratio is obtained in a totally white display mode.
