A method for manufacturing a micro-lens array substrate according to the present
invention includes the steps of: (1) disposing a stamper having a first micro-lens
array pattern formed on one surface of the stamper and a second micro-lens array
pattern formed on other surface of the stamper between a first transparent substrate
and a second transparent substrate facing each other; and (2) removing the stamper,
after forming micro-lens arrays which are made of first and second light transmitting
resins respectively between the first transparent substrate and the stamper and
between the second transparent substrate and the stamper, so as to fix a third
light transmitting resin between the two micro-lens arrays, thereby manufacturing
a micro-lens array substrate. This eliminates the need for adjustment of optical
axes of the micro-lens arrays which are formed respectively on the first and second
transparent substrates, thus simplifying the steps for the manufacture of a micro-lens
array substrate and realizing efficient mass production of a micro-lens array substrate
with a high degree of accuracy.
