摘要： PROBLEM TO BE SOLVED: To provide a screen which allows an observation distance to be adjusted while brightness of an image is being maintained, and further to provide a projection system using the screen.SOLUTION: In an optical control layer 3 of a screen 10, a first angle region ω which determines diffusion distribution of reflected light is set to be different for different positions on the screen 10 regarding a control direction D1 for performing diffusion control of light. On account of this, by adjusting diffusion distribution of image light emitted from a surface of the screen 10, in response to a position on the screen 10, to be greatly inclined toward a lower side as the position is closer to an upper end UE side and to be greatly inclined toward an upper side as the position is closer to a lower end BE side, for example, a direction in which the image light is diffused and emitted is set to correspond to a position of an observer assumed with magnitude of an angle range to be diffused remaining 30° without any change in angle, a projection image can be observed while brightness of an image is being maintained and an observation distance L can be adjusted to be shortened.

Thus, the light transmitting surface TS can transmit external light OL entering from various directions in the periphery of the screen 10 to be absorbed in a screen base plate 1, whereby influence due to reflection of external light OL can be reduced and the contrast can be more improved.

摘要： PROBLEM TO BE SOLVED: To provide a projector which projects an easy-to-view color image by making the response speed of a liquid crystal panel higher.
SOLUTION: A liquid crystal light valve 31 is equipped with a pair of thin liquid crystal panel parts 61 and 62, so that the response speed of optical modulation is made higher than in the ordinary liquid crystal light valve 31. Generally speaking, the response speed of the liquid crystal element is decreased as the viscosity of liquid crystal is increased. When a TN mode is obtained by two liquid crystal panel parts 61 and 62, therefore, the thickness of the liquid crystal layers is 1/2 of the ordinary one, so that the response speed of the liquid crystal element is doubled.
