Abstract: A laminated display unit having a light guide, an LCD panel laminated to a major surface of the light guide and a high modulus layer laminated to the light guide opposite the LCD panel. A first material having refractive index n1 is disposed immediately adjacent a first major surface of the light guide and a second material having a refractive index n2 is disposed immediately adjacent a second major surface of the light guide. The light guide has a refractive index ng which is greater than about 1.05 times nmax where nmax is the larger of n1 and n2. At least one of the first major surface and the second major surface includes a plurality of multiplets where each multiplet includes two or more extraction features.
