ABSTRACT:
An object of the invention is to provide a method of manufacturing a microlens array and a projection-type liquid crystal display apparatus which can increase the efficiency of use of light, facilitate a method of manufacturing a microlens array and reduce the cost of equipment. By an operation of only irradiating a first lens with parallel light which has an intensity distribution corresponding to the shape of a second lens and irradiating an ultraviolet curing resin layer with transmission light, the first and second lenses are placed with a high alignment accuracy in a mutual positional relation thereof. By irradiating the first lens with the parallel light, it becomes possible to uniformly expose a broad area, and it becomes possible to expose by the wafer.
