Claim:
1. A display device comprising: a device substrate arranged with a plurality of pixels and a bank layer; and a color filter substrate includes a color filter layer with different transparent wavelength bands corresponding to each of the pixels, a first light shielding layer, and a second color filter layer; wherein each of the plurality of pixels includes a light emitting device having a pixel electrode, an organic electroluminescence layer, and an upper part electrode; the bank layer arranged on the boundary region of the plurality of pixels, the bank layer covering a peripheral portion of the pixel electrode; the color filter layer arranged above a translucent support substrate, the color filter layer includes a first color filter layer having a first transparent wavelength band, a second color filter layer having a second transparent wavelength band, and a third color filter layer having a third transparent wavelength band; the first light shielding layer arranged corresponding to a boundary region of the plurality of pixels and surround the plurality of pixels, the second light shielding layer arranged to overlap the first light shielding layer and surrounding the plurality of pixels, and the first light shielding layer and the second light shielding layer sandwiching the color filter layer with no other layer in between; the first light shielding layer is arranged corresponding to each of a boundary region of the first color filter layer, the second color filter layer, and the third color filter layer, and the first light shielding layer is arranged over the surface opposite to the second light shielding layer of the color filter layer, and the second light shielding layer overlaps the first light shielding layer in a plan view and the second light shielding layer arranged over the bank layer; the second light shielding layer having a higher transparency than the first light shielding layer and a lower transparency than the translucent support substrate; and the second light shielding layer is wider than the first light shielding layer and is arranged on the side of the light emitting device than the first light shielding layer.
