Abstract:
1. A display device for displaying a first view and a second view, each of the first view and the second view having a respective horizontal viewing angle and a respective vertical viewing angle, the display device comprising: a color generating layer; a barrier layer (SB a light source; a plurality of non-transparent metal connection lines (M); and a plurality of delineation elements (BM); the color generating layer comprising a plurality of color elements of at least red elements, green elements, and blue elements, the plurality of color elements being arranged as pixel elements, each pixel element comprising at least one of the red elements, one of the green elements and one of the blue elements, the pixel elements being arranged in a horizontal direction and in a vertical direction; each color element having a pitch (Py) in the vertical direction; the light source being arranged such that, during use, light generated by the light source passes through the barrier layer and the plurality of color elements of the color generating layer; the barrier layer, comprising a stepped barrier pattern of blocking structures and openings extending in the horizontal and the vertical directions, being arranged for defining a viewing angle of the first view and a viewing angle of the second view; the blocking structures having a blocking width in the vertical direction, the openings having an opening width in the vertical direction; the opening width in the vertical direction being either equal to or smaller than the pitch (Py) of one of the plurality of color elements in the vertical direction; and the light source being arranged for generating collimated light; each non-transparent metal connection line (M) being located at an interface area between two vertically adjacent ones of the plurality of color elements; each the non-transparent metal connection line (M) being covered by and being in direct contact with one of the delineation elements (BM); and vertical width (Wby) of delineation elements (BM) being larger than vertical width (Wmy) of the non-transparent metal connection lines (M).
