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.
Claims10
A liquid crystal display device which comprises:
- a first substrate;
- a plurality of picture element electrodes arranged in a matrix formed on an inner surface of the first substrate;
- a plurality of switching elements wherein each one of said plurality of picture element electrodes is associated with a corresponding one of said plurality of switching elements;
- a plurality of lens elements formed on the inner surface of the first substrate, each lens element being separately disposed under a corresponding picture element electrode;
- a second substrate opposed to the first substrate;
- and
- a liquid crystal layer disposed between the first substrate and the second substrate,
- wherein said plurality of lens elements are formed on a same plane with said plurality of switching elements.
A liquid crystal display device which comprises:
- a first substrate comprising an insulating substrate, a plurality of display elements formed in rows and columns on the first substrate, each of said plurality of display elements comprising a picture element electrode, a switching element electrically connected to the picture element electrode, and a lens element deposited between the first substrate and the picture element electrode;
- a second substrate opposed to the first substrate and having an electrode formed on an inner surface thereof;
- and
- a liquid crystal layer sandwiched between the first substrate and the second substrate,
- wherein said plurality of lens elements are formed on a same plane with said plurality of switching elements.
