摘要
A liquid crystal panel unit (2) includes, on its side from which light enters, a micro-lens substrate (1) having: a first micro-lens array including a first lens (5) for converging, for converging, on aperture sections (17R•17G•17B) of respective picture elements in a liquid crystal display element, the plurality of the light beams whose respective incident angles are different from one another; and a second micro-lens array having a second lens (7) for collimating principal rays of the respective light beams. The second lens (7) is substantially trapezoid so that the lens includes slanted surfaces (7b•7b) directing its convex parts towards the light incident side. With this configuration, it is possible to realize a single-panel mode color-filterless projection-type liquid crystal display device with high light-using efficiency at a low cost, without deteriorating the light-using efficiency.
