PURPOSE: A transmissive screen of a projection TV is provided to prevent a lenticular sheet from bending or being warped due to temperature and humidity, by a filter adhered to the lenticular sheet. CONSTITUTION: A fresnel sheet(9) condenses beam reflected through a reflective mirror and projects the condensed beam to a lenticular sheet incident plane(11). A lenticular sheet(10a) controls horizontal and vertical light distribution characteristics of the condensed and incident beam to be dispersed by a diffusion material distributed on an emitting plane(12) for realizing the optimum image. A filter(13) improves contrast of a screen(5a), protecting the lenticular sheet. A material of the lenticular sheet is larger than a material of the filter in a moisture absorbing rate. The lenticular sheet and the filter are bonded by an adhesive.
