LIQUID CRYSTAL CELL AND PROJECTION LENS ASSEMBLY AND IMAGE PROJECTION DEVICE HAVING THE SAME

摘要

PURPOSE: A liquid crystal cell and projection lens assembly and an image projection device having the same are provided to precisely adjust positions of a liquid crystal cell and a projection lens. CONSTITUTION: A liquid crystal cell and projection lens assembly(100) includes liquid crystal cells, a substrate(32) and a projection lens(36), which are fixed by a carrier(20), respectively. The carrier(20) is provided at upper and lower portions thereof with a frame having a bar shape. An analyzer(34) is attached to one surface of the substrate(32). The liquid crystal cells are spaced from the substrate(32) and the analyzer(34) is spaced from the substrate(32) while forming air gaps(38a,38b). The liquid crystal cells are sequentially aligned while being surrounded by the carrier(20).
