A filter is arranged that has a difference in transmittance in different directions, and the transmittance decreases toward the center of the tube of the tubular light source, and at least one of the filters has a transmittance that decreases toward the center of the tube of the tubular light source. 1. A transmissive display device, characterized in that a convex portion is formed that protrudes toward the viewer, so that the filter and the tubular light source come into contact with each other through the convex portion. (2) A transmissive display device according to claim 1, wherein a filter having a convex portion protruding toward the tubular light source toward the vicinity of the center of the tube of the tubular light source is disposed. (3) The transmissive display device according to claim 2, wherein the convex portion is formed by the filter itself. (4) Utility model registration claim 3 in which the convex portion is formed by applying pressure from the opposite side of the filter
Transmissive display device as described in . (5) The transmission type display device according to any one of claims 1 to 4 of the utility model registration claim, wherein the filter is separately arranged on the back surface of the diffuser plate. (6) The transmissive display device according to claim 5, wherein the filter is a film with an opaque layer provided thereon, and the transmittance is changed depending on the area of the opaque layer per unit area. (7) The transmissive display device according to claim 6, wherein the opaque layer is a metal reflective layer.
