Abstract:
1. An array display apparatus comprising: display devices each including a display section capable of displaying an image, and a non-display area located around the display section and incapable of displaying an image; and transparent plates each disposed nearer to the viewer than the display section of a corresponding display device and covering the display section and the non-display area of the corresponding display device, wherein the display devices and the transparent plates each have a polygonal shape when viewed in a normal direction of a display surface of the display section, wherein adjacent transparent plates are disposed in contact with each other, wherein each transparent plate has: a light exit-side deflection portion for inwardly bending a traveling direction of at least part of light that has exited the display section and passed through the transparent plate, said light exit-side deflection portion being provided at least in an area of a peripheral part of a viewer-side surface, the area facing the non-display area when viewed in the normal direction of the display surface of the display section; corner deflection portions, provided at the corners of the viewer-side surface, for inwardly bending a traveling direction of at least part of light that has exited the corresponding display section and passed through the transparent plate, wherein the light exit-side deflection portion has a width larger than a width of the non-display area, wherein the light exit-side deflection portion has a curved surface, curved surfaces arranged in an inner-outer direction, inclined surfaces arranged in the inner-outer direction, or at least one curved surface and at least one inclined surface arranged in the inner-outer direction, and wherein in the light exit-side deflection portion, an angle formed between a tangent plane of a curved surface at a point on the deflection portion and a plane parallel to the display surface of the display section or an angle formed between an inclined surface at a point on the deflection portion and a plane parallel to the display surface of the display section increases as the point moves outward in the inner-outer direction, wherein the corner deflection portions each have a curved surface, curved surfaces arranged in the inner-outer direction, inclined surfaces arranged in the inner-outer direction, or at least one curved surface and at least one inclined surface arranged in the inner-outer direction, wherein in each corner deflection portion, an angle formed between a tangent plane of a curved surface at a point on the deflection portion and a plane parallel to the display surface of the display section or an angle formed between an inclined surface at a point on the deflection portion and a plane parallel to the display surface of the display section increases as the point moves outward in the inner-outer direction, and wherein when viewed in the normal direction of the display surface of the display section, an innermost point on each corner deflection portion lies on an outer side of an innermost point on the light exit-side deflection portion wherein the corner deflection portions are each inclined with respect to the light exit-side deflection portions and enhance image continuity at corners of the transparent plates.
