Abstract
It is intended to provide a liquid crystal display of high luminance and a manufacturing process of such a liquid crystal display which is simple and easy to manufacture, of which focal distance can be easily adjusted, and which is provided with microlens not giving rise to lowering of yield due to sticking of dust, etc. In an IPS type liquid crystal display in which a lower transparent insulating substrate 1, on which condensing lens 6 and a flattening layer 7 made of materials of different refractive indexes are formed, and an upper transparent insulating substrate 2, on which picture element electrodes 4, 5 are formed, are arranged to be opposite to each other, and a liquid crystal layer 3 is held between the lower and upper transparent insulating substrates, tapered portions 6b of the condensing lens 6 formed by etching a condensing lens layer 9 are arranged to be opposite to regions where picture element electrodes 4, 5 are formed.
