Abstract
In fabricating a microlens array, a transparent resin layer is formed on surfaces of microlenses by coating a phenol resin layer that chemically reacts with the microlenses and thereafter removing the phenol resin layer. Since the transparent resin layer is generated by chemical reaction with the microlenses, the transparent resin layer can be uniformly formed on the surfaces of the microlenses without deformation of the microlens and deterioration in material thereof. Therefore, the microlens array has the uniform microlenses in shape and quality, a short lens interval and a small ineffective region between the microlenses to obtain a high light condensation rate.
Claims8
A microlens array having a plurality of microlenses formed of a transparent resin, wherein
- a surface of the microlenses is uniformly covered with a transparent resin layer.
A microlens array fabricating method comprising the steps of:
- processing a microlens material layer into a pattern corresponding to a plurality of microlenses;
- forming the material layer into the plurality of microlenses by reflow of the material layer processed according to the pattern;
- and
- uniformly forming a transparent resin layer along the surface of the plurality of microlenses.
