Abstract
A liquid crystal display (LCD) panel has apertures for entry of backlight. A micro-lens array comprises micro-lenses of a resin on a transparent base. The base and each of the micro-lenses have a surface energy difference falling in or constrained to a predetermined range. The shape of each of the micro-lenses is such that collimated light substantially orthogonally incident to each of the micro-lens is compressed into a tight beam to enter one of the apertures.
