Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 使用目的に応じて最適の画像表示を可能にす る投射型表示装置を提供すること。 【解決手段】 赤色画像用の画像表示素子8Rとダイク ロイックミラーDM2との間の光路中に600nm以上 の波長を透過しそれ以外の波長領域を阻止する特性を有 するエッジフィルタSC1を挿脱できるようにしてお き、フィルタSC1を光路中に置いて色純度を優先させ た表示を行ない、フィルタSC1を光路外に置いて画像 表示素子8B,8G,8Rの制御方式をフィルタSC1 を光路中に置く時とは変えることにより自然な色合いの 明るさを優先させた表示を行なう。 (57) [Problem] To provide a projection display device capable of displaying an optimal image according to a purpose of use. SOLUTION: An edge filter SC1 having a characteristic of transmitting a wavelength of 600 nm or more and blocking a wavelength region other than 600 nm in an optical path between an image display element 8R for a red image and a dichroic mirror DM2 can be inserted and removed. The filter SC1 is placed in the optical path to perform display with priority given to color purity, and the filter SC1 is placed outside the optical path to control the image display elements 8B, 8G, and 8R. Is displayed in a light path by changing the color of the light in the optical path.
