Abstract: The present invention relates to an area light source device and a display device using the area light source device. The present invention includes a point light source, and a light guide plate. The light guide plate includes a protruding structure on a light entrance surface side. The protruding structure protrudes from a light exit surface side or a counter light exit surface side opposite from the light exit surface. The point light source includes an arrangement of point light sources. The protruding structure is configured such that oblique cylinders each having a semicircular upper surface protrude and arranged in a direction of the arrangement of the point light sources. The point light sources are arranged so that the lines of intersection of adjacent ones of the oblique cylinders coincide with the middles of the point light sources, respectively.

Abstract: A display device of the present invention includes a display element having a display surface, a frame that houses the display element and has an opening exposing the display surface, a plurality of adhesive members linearly bonded with gaps therebetween to a surface on a periphery of the opening of the frame along the opening, the surface being opposite to the display element, a touch panel that is fixed to the frame through the adhesive members so as to cover the opening, and a resin that is applied to the frame so as to fill the gaps and is in contact with the touch panel.
