A direct-viewing type display device includes: a display panel 10 having a display region 10A and a frame region 10F provided outside the display region, with a boundary extending along a first direction between the display region and the frame region, the display region having a plurality of pixels arrayed therein; and a light-transmitting cover 14 disposed on the viewer's side. The light-transmitting cover includes a lens portion 141 disposed astride the boundary for refracting a portion of light going out from the display region toward the frame region. The lens portion refracts the light so that light emitted from the plurality of pixels in the display region has a substantially equal pitch on a plane which is perpendicular to the first direction. A line of intersection 1412 between the plane which is perpendicular to the first direction and a viewer-side surface 1411 of the lens portion is a curve which is not a circular arc. According to the present invention, with a simpler structure than conventionally, there is provided a display device that displays an undistorted image, in which the frame region, or joints in the case of tiling, is obscured.
