Abstract
An MVA-type LCD capable of displaying with a high contrast ratio is provided. An LCD according to the present invention is an MVA-type LCD including a stripe-shaped rib 21b provided on a first electrode 11 of a liquid crystal layer and a stripe-shaped slit 22 formed in a second electrode 12 of the liquid crystal layer. The rib 21b has a side face whose taper angle in a cross section which is orthogonal to an azimuth direction that the rib 21 extends is 18° or less, and is made of a material such that a film of the material with a thickness corresponding to the height of the rib has an OD value of 0.8 or more.
Claims9
A liquid crystal display device comprising a plurality of pixels each including a first electrode, a second electrode opposing the first electrode, and a vertical-alignment type liquid crystal layer provided between the first electrode and the second electrode, wherein,
- each of the plurality of pixels includes:
- a stripe-shaped rib provided on the first electrode on the liquid crystal layer and
- a stripe-shaped slit formed in the second electrode on the liquid crystal layer;
- when a voltage is applied across the liquid crystal layer, a liquid crystal domain is formed such that an azimuth direction of tilting of liquid crystal molecules in a region between the rib and the slit is orthogonal to an azimuth direction that the rib and the slit extend;
- and
- the rib has a side face whose taper angle in a cross section which is orthogonal to an azimuth direction that the rib extends is 18° or less, and is made of a material such that a film of the material with a thickness corresponding to a height of the rib has an OD value of 0.8 or more.
