LIGHT DIFFUSING SUBSTRATE AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a light diffusing substrate which does not decrease the diffusing performance even when various kinds of apparatuses having different sizes of minimum display pixels are manufactured. SOLUTION: The diffusing substrate is manufactured by applying a photosensitive resin on a transparent substrate for a liquid crystal display panel, exposing the photosensitive resin through an exposure mask and developing the resin to from a diffusing layer having a diffusing pattern composed of minute recesses and projections. In the above method, the mask pattern of the exposure mask is manufactured by repeatedly drawing a basic pattern BP in a specified size by a beam drawing machine while forming a blank BL of 1 to 5μm width in the boundary part between adjacent basic patterns.
