摘要： When the DVD provided with the DVD substrate 2 having thickness t2 of 0.6 mm is installed in the optical disc apparatus, the light beam 4 having wavelength λ1=655 nm is used as luminous flux of numerical aperture NA=0.63 to be condensed on the information surface 2a on the DVD substrate 2. When the CD provided with the CD substrate 3 having thickness t2 of 1.2 mm is installed in the optical disc apparatus, the light beam 5 having wavelength λ2=790 nm is effectively used as luminous flux of approximate numerical aperture NA=0.45 to be condensed on the information surface 3a on the DVD substrate 3. The wavefront aberration caused by a thickness difference between the DVD substrate 2 and CD substrate 3 is canceled out by the chromatic aberration caused by a wavelength difference between the light beams 4 and 5. Therefore, in spite of the difference in the transparent substrates, the light beams are suitably condensed respectively on the information surface 2a and 3a.

摘要： A liquid crystal display includes an illumination optical system which has a light source for emitting light and acts to irradiate the light from the light source on a light bulb on which an optical image is formed in accordance with a video signal, and a transmission-type liquid crystal display element for displaying the image information by the electrooptical effect of the liquid injected between a pair of transparent substrates of the light bulb. The liquid crystal display element is formed of a micro-lens array which has unit lenses provided to oppose the respective picture elements of the picture element array of the liquid crystal and thus to have the same array as the picture element array of the liquid crystal. Since this micro-lens array is closely attached to the side of liquid crystal display element to which the luminous flux emitted from the light source is incident, or integrally formed within the liquid crystal cell substrate, the liquid crystal display element has a high aperture ratio.
