摘要： A liquid crystal rear-projection TV screen has a double-side lens sheet and horizontal lenticular sheet. A vertical lenticular portion is disposed on the rear side of the double-side lens sheet, and Fresnel lens is disposed on the front side. A horizontal lenticular portion is disposed on the rear side of the horizontal lenticular sheet, and a light-shielding layer and protective resin substrate are disposed on the front side. The resin substrate of the double-side lens sheet has a low transmittance, and the resin substrates of the horizontal lenticular sheet have high transmittances. The observer recognizes an image on the double-side lens sheet arranged behind the light-shielding layer.

摘要： A method for producing carbamates that enables carbamates to be produced at low costs, with high selectivity and high yield, and in a simple manner, and a method for producing isocyanates that enables isocyanates industrially used to be produced by using the carbamates obtained by the carbamates producing method. Nonaromatic amine selected from the group consisting of aliphatic amine, alicyclic amine, and aralkyl amine is allowed to react with alkylaryl carbonate to thereby produce carbamates. Also, the carbamates thus obtained are thermally decomposed to thereby produce isocyanates. When carbamates are produced in this method, alkyl carbamates can be obtained with high selectivity and at high yield by using simple equipment. Also, when isocyanates are produced in this method, polyisocyanates used industrially as the raw material of polyurethane can be produced in a simple manner and with efficiency.
