Patent ID: 8472114

Claim:
A direct-viewing type display device comprising: at least one display panel having a display region including a matrix array of a plurality of pixels arranged along a row direction and a column direction and a frame region provided outside the display region, such that a first border line extending along the row direction and a second border line intersecting the first border line and extending along the column direction exist between the display region and the frame region; and at least one light-transmitting cover disposed on a viewer's side of the at least one display panel, wherein, the display region is composed of a peripheral display region adjoining the frame region and a central display region, the central display region defining a region other than the peripheral display region; a third border line extending along the row direction and a fourth border line intersecting the third border line and extending along the column direction exist between the peripheral display region and the central display region; the peripheral display region includes a first peripheral display section surrounded by a straight line passing through a point where the third border line and the fourth border line intersect and orthogonally intersecting the first border line, a straight line passing through the intersecting point and orthogonally intersecting the second border line, the first border line, and the second border line; the at least one light-transmitting cover includes a lens portion disposed over the peripheral display region and the frame region, the lens portion allowing light going out from at least one pixel within the first peripheral display section to be refracted in a direction from the intersecting point toward the at least one pixel; the frame region includes a first frame portion surrounded by a straight line passing through the intersecting point and orthogonally intersecting the first border line, a straight line passing through the intersecting point and orthogonally intersecting the second border line, the first border line, the second border line, and an outer edge of the frame region; the lens portion includes a first lens body disposed over the first peripheral display section and the first frame portion; and the first lens body is a portion of a solid obtained by cutting a body of revolution in two planes containing an axis of revolution, the axis of revolution passing through the intersecting point and being perpendicular to the third border line and the fourth border line.
