Display device

A direct-viewing type display device, comprising:

• a display panel including a display region which includes a plurality of pixel lines extending in a first direction and a frame region provided outside the display region, the display region and the frame region having a border extending in the first direction therebetween;
• and
• a light-transmitting cover located on a viewer's side of the display panel;
• wherein:
• the plurality of pixel lines include a first pixel line adjoining the border, a second pixel line adjoining the first pixel line, and a third pixel line adjoining the second pixel line;
• the first pixel line, the second pixel line and the third pixel line are of different colors from each other;
• the light-transmitting cover includes a lens portion located so as to stride over the border, the lens portion refracting a portion of light, going out from the display region, toward the frame region;
• a light diffusion structure is provided between the lens portion and a portion of the display panel including the first pixel line, the second pixel line and the third pixel line;
• and
• the light diffusion structure comprises an adhesive layer and particles mixed in the adhesive layer;
• and
• the light diffusion structure includes a low light diffusion region on a side of the display region, the low light diffusion region being formed such that a light diffusion degree thereof increases continuously or step by step from the side of the display region toward the frame region.
