PROBLEM TO BE SOLVED: To provide a display that is robust and easy to use for faithfully imitating a human visual system.SOLUTION: A display unit comprises: at least one context display for rendering a context image; at least one focus display for rendering a focus image; at least one optical combiner for combining projection of the rendered context image and projection of the rendered focus image to create a visual scene; means that detects the direction of a line of sight; and a processing part that is connected to communicate with the at least one optical combiner and the means that detects the direction of a line of sight. The angle width of the projection of the rendered context image is within a range of 40 degrees to 220 degrees, and the angle width of the projection of the rendered focus image is within a range of 5 degrees to 60 degrees.SELECTED DRAWING: Figure 4A
