Abstract
A reflection-type liquid-crystal display with a reflection-type liquid-crystal display panel, which comprises a transparent view-side substrate with a transparent electrode and a transparent backside substrate with a transparent electrode that are so combined as to have a liquid crystal between the facing electrodes thereof to construct a liquid-crystal cell, and comprises a transparent optical film having a radius of curvature at break of at most 5 mm, on the outer side of the view-side substrate via a polarizing layer therebetween, and a reflection layer on the outer side of the backside substrate, and which is characterized in that the optical film has, in its surface, a plurality of optical path-changing slopes that incline at an angle of from 35 to 48 degrees relative to the standard plane of the view-side substrate, and one or more sides of the optical film have a light source; and the optical film.
