Sheet and light emitting apparatus
A sheet of the present invention is a sheet which is to be used such that light from a light emitting body impinges on one of surfaces of the sheet and outgoes from the other surface. The other surface of the sheet includes a plurality of minute regions 13, a largest inscribed circle of the minute regions 13 having a diameter from 0.2 μm to 2 μm. Each of the plurality of minute regions 13 is adjoined by and surrounded by some other ones of the plurality of minute regions 13. The plurality of minute regions 13 include a plurality of minute regions 13a which are randomly selected from the plurality of minute regions 13 so as to constitute 20% to 80% of the minute regions 13 and a plurality of minute regions 13b which constitute the remaining portion of the minute regions 13. Light transmitted through the plurality of minute regions 13a and light transmitted through the plurality of minute regions 13b have a phase difference of π.
