ABSTRACT:
A reflective or transmissive image display device having a light-transmissive panel to which illuminating light for illuminating pixels is applied. The light-transmissive panel has laminated glass substrates having respective first and second planar microlens arrays. The glass substrates have their thicknesses adjusted by grinding to equalize focal lengths and other parameters of the first and second planar microlens arrays to preset values. Lenses of the first and second planar microlens arrays are formed by etching recesses in fire-finished surfaces of the glass substrates and filling the recesses with a synthetic resin having a high refractive index.
