Abstract: A method of producing a long polarizer by which a polarizer serving as a final product that can achieve the multi-functionalization and high-functionalization of an electronic device, such as an image display apparatus, and that is free of any variation in quality can be produced at low cost and with high productivity. A method of producing a long polarizer having non-polarization portions according to an embodiment of the present invention includes; laminating, on one surface of a long polarizer, a long surface protective film having through-holes arranged in a lengthwise direction and/or a widthwise direction at predetermined intervals to form a long polarizing film laminate; partially decoloring the polarizer through the through-holes of the surface protective film to form the non-polarization portions; and removing the surface protective film.

Abstract: The room includes: a ceiling; a floor; and a wall having a pair of wall surfaces opposite to each other, and another pair of wall surfaces opposite to each other in a direction intersecting the pair of wall surfaces. One of the pair of wall surfaces and the other pair of wall surfaces has a window. The wall surface opposite to the wall surface having the window has arranged thereon a first screen. An inner side of the window, and a projection-side surface of the first each has arranged thereon a polarizing plate. An absorption axis direction of a polarizer of the polarizing plate of the window, and an absorption axis direction of a polarizer of the polarizing plate of the first screen and/or an absorption axis direction of a polarizer of the polarizing plate of the second screen are substantially perpendicular or parallel to each other.
