This invention relates to a projection system (300) and a liquid crystal display comprising a reflection device (100, 200, 308) adapted to received incoming light (102, 210, 304), to decompose the incoming light (102, 210, 304) into three primary light colours, and to individually reflect and modulate each of the primary light colours. The reflection device (100, 200, 308) comprises a stack of layers in co-planar relationship and defining a longitudinal axis normal to the incoming light (102, 210, 304). The stack of layers receives the incoming light (102,210,304) and comprises for each of the primary light colours a transmissive modulating layer (108, 116, 124, 202, 204, 206, 314, 320, 326) and a colour sensitive reflective layer (110,118,126,214,222,230,310,316,322).
