摘要： A rear-projection screen for a rear-projection image display apparatus comprises a Fresnel lens sheet, a first lenticular lens sheet, and a second lenticular lens sheet or a Fresnel lens sheet, first and second lenticular lens sheets and a light absorbing sheet. A light entrance surface of the first lenticular lens sheet or a light exit surface thereof, or both of these surfaces are formed by contiguously and vertically arranging a plurality of horizontally elongate lenticular lenses. A thickness of the first lenticular lens sheet is selected to be the thinner than thicknesses of the Fresnel lens sheet, the second lenticular lens sheet, and the light absorbing sheet. The entrance surface and the exit surface of the second lenticular lens sheet are formed by contiguously and horizontally arranging a plurality of vertically elongate lenticular lenses. Particles of a light diffusing material are not necessarily dispersed in the base sheet of the second lenticular lens sheet. The rear-projection image display apparatus provided with this rear-projection screen has satisfactory focusing characteristics and enhanced vertical directional characteristics and is capable of displaying an image in high brightness and high contrast.

摘要： A glass substrate for packing liquid crystals includes a mechanically treated surface covered by a transparent coating. This ensures that the glass substrate has a high transparence. A method for manufacturing such a glass substrate includes the steps of: (a) providing an original glass substrate including a mechanically treated surface having a plurality of dents; and (b) forming a transparent coating on the surface to fill the dents. The steps can be completed in a relatively short time, and thus the manufacturing cost is reduced. An LCD device using such glass substrates includes a plurality of liquid crystals and two glass substrates packing the liquid crystals therebetween.
