Abstract
A method of manufacturing a micro lens array comprising a step of forming a color pattern layer including a plurality of pixels in a predetermined arrangement on a light transmitting substrate, and a step of curving surfaces of the pixels in the color pattern layer corresponding to lens surfaces, wherein in the step of curving the surfaces of the pixels, the pixels are melted by heating to cause the surfaces of the pixels to convexly curved by surface tension.
Claims5
A method of manufacturing a micro lens array comprising the steps of:
- dropping a liquid on a substrate by an ink jet method;
- convexly curving a surface of the liquid by at least one of surface tension and repellence;
- and
- solidifying the liquid to form a convex lens.
