| 摘要 |
The present invention provides a microlens array produced by molding a resin obtained by reacting a silicon compound with a boron compound or an aluminum compound, in which the silicon compound is represented by the following formula (I): in which R1 and R2 each independently represent an alkyl group, a cycloalkyl group, an alkenyl group, an alkynyl group, or an aryl group, in which a plurality of R1's are the same or different and a plurality of R2's are the same or different; X represents a hydroxy group, an alkoxy group, an alkyl group, a cycloalkyl group, an alkenyl group, an alkynyl group, or an aryl group; and n is 4 to 250. This microlens array has excellent heat resistance and light resistance even when applied to LEDs having an increased power and to LEDs emitting blue light having a short wavelength.
