<P>PROBLEM TO BE SOLVED: To enhance the light-condensing properties of a microlens with respect to pixel, provided to a microlens array. <P>SOLUTION: A plurality of microlenses are arrayed on the microlens array plate. Each of the plurality of microlenses is provided with a first part which is composed of a first transparent medium having a first refractive index, regulates a first lens curved surface and has either one side shape that is concave or convex; and a plurality of second parts which are integrally formed of the first transparent medium to the first part, respectively prescribe second lens curved surfaces located a little to the surrounding of the first lens curved surface as seen in a plan view on the microlens array plate and respectively have either one side shape that is concave or convex, being the same kind with the above-mentioned one side shape. <P>COPYRIGHT: (C)2007,JPO&INPIT |
