Abstract:
An active matrix liquid crystal display device comprising a liquid crystal cell, a switching element arranged in matrix, and shading layers mounted both on the upper side and the lower side of said switching element; the upper shading layer including an upper sloped portion and having a convex shape protruding toward said switching element, the lower shading layer having a flat shape: whereinsaid upper shading layer is formed so that said upper sloped portion is located at a &thgr;1 angle to the horizontal direction, and said upper sloped portion has a horizontal direction length of 111; said lower shading layer is formed so that the length from the end of said lower shading layer to the point that the line drawn downward to the vertical direction from the origin of said upper sloped portion crosses said lower shading layer is 112; and the maximum incident angle of the light traveling obliquely from the upper shading layer side is &agr;1, the maximum incident angle of the light traveling obliquely from the lower shading layer side is &bgr;1, and the distance between the upper shading layer and the lower shading layer is d1; in which &thgr;1, 111 and 112 each fulfill&thgr;1>&bgr;1, â€ƒ111>(112+d1Â·tan &agr;1)/(1âˆ’tan &thgr;1Â·tan &agr;1), and112>d1Â·tan &bgr;1.
