LCD microlens substrate with a lens array and a uniform material bonding member, each having a thermal resistance not lower than 150amp;deg;C

摘要

The present invention discloses an opposed substrate for use in a liquid crystal display element, for example. The opposed substrate is constructed by a transparent substrate, microlenses formed on the substrate, a bonding layer, and cover glass. An alignment film and transparent electrodes are formed on the cover glass. The microlenses and the bonding layer are formed by selected resins which have thermal resistance to high temperatures not lower than 150° C., permit heating treatment for forming the alignment film, and satisfy the difference in the refractive indexes between the resins, .increment.n. gtoreq.0.1, so as to enable the microlenses to have a numerical aperture not lower than 0.1. It is thus possible to prevent the decomposition of resins and separation of the microlens in heat treatment and to provide a high-quality, highly reliable liquid crystal display element.
