线栅型无机偏振板的安装结构及使用其的投射型影像显示装置
摘要：
本发明提供线栅型无机偏振板的安装结构及使用其的投射型影像显示装置，其目的在于简化线栅型无机偏振板的安装结构并实现高价的线栅型无机偏振板的有效利用。在本发明的线栅型无机偏振板的安装结构中，在支架(31B)的平面部(31Ba)设有使光通过的开口部(31Bb)，并且安装成线栅型的无机偏振板(31A)的玻璃基板(31Aa)与保护该偏振板的金属制元件(31Ab)的表面保护基材(31C)隔着该支架(31B)的平面部(31Ba)。如此，线栅型无机偏振板(31A)的金属制元件(31Ab)插入开口部(31Bb)内。另外，本发明的投射型影像显示装置在至少一个部位使用以该结构安装的线栅型的无机偏振板(31A)。
摘要（英）：

The invention provides a coupling structure for a wire grid type inorganic polarizer and a video projector including the same, the coupling structure and the video projector aim at simplifying the coupling structure of the wire grid type inorganic polarizer and realizing effective utilization of the wire grid type inorganic polarizer. The coupling structure includes a holder (31B) and a wire grid type inorganic polarizer (31A). The holder includes a flat portion (31Ba) and an open portion (31Bb) through which light passes, a glass substrate (31Aa) installed to be a wire grid type inorganic polarizer (31A) is separated from a surface protection base material (31C) protecting a metal element (31Ab) of the polarizer via the holder (31B). In the above way, the metal element (31Ab) of the wire grid type inorganic polarizer (31A) is inserted in the open portion (31Bb). Additionally, the video projector uses the wire grid type inorganic polarizer (31A) in the coupling structure at at least one part.
