DISPLAY DEVICE
According to one embodiment, a display device includes a plurality of pixels, an insulating substrate, an organic electroluminescent element, a sealing layer, color filter layers located on the sealing layer and including a first color filter of a first color, a second color filter of a second color, and a third color filter of a third color, a first pixel aperture where the first color filter is located, a second pixel aperture where the second color filter is located, and a third pixel aperture where the third color filter is located, in each of pixels, and a light-shielding area surrounding each of the first to third pixel apertures, in which the first to third color filters are stacked one on another.
1 . A display device comprising:
a plurality of pixels;
an insulating substrate;
an organic electroluminescent element located on the insulating substrate and including an organic light emitting layer;
a sealing layer sealing the organic electroluminescent element;
color filter layers located on the sealing layer and including a first color filter of a first color, a second color filter of a second color different from the first color, and a third color filter of a third color different from the first color and the second color;
a first pixel aperture where the first color filter is located, a second pixel aperture where the second color filter is located, and a third pixel aperture where the third color filter is located, in each of the plurality of pixels; and
a light-shielding area surrounding each of the first pixel aperture, the second pixel aperture, and the third pixel aperture, in which the first color filter, the second color filter, and the third color filter are stacked one on another.
2 . The display device of claim 1 , further comprising:
a display surface on an opposite side to the insulating substrate with respect to the organic electroluminescent element,
wherein
the first color filter, the second color filter, and the third color filter are stacked one on another in the light-shielding area from a side of the insulating substrate toward a side of the display surface.
3 . The display device of claim 1 , wherein
the first color filter includes a first aperture at a position overlapping the third pixel aperture and a second aperture at a position overlapping the second pixel aperture,
the second color filter includes a third aperture at a position overlapping the third pixel aperture and a fourth aperture at a position overlapping the first pixel aperture, and
the third color filter includes a fifth aperture at a position overlapping the first pixel aperture and a sixth aperture at a position overlapping the second pixel aperture.
4 . The display device of claim 1 , further comprising:
an overcoat layer located between the sealing layer and the color filter layers,
wherein
the overcoat layer includes a groove portion overlapping the light-shielding area,
the first color filter, the second color filter, and the third color filter are stacked on top of each other at positions overlapping the groove portion, and
a part of the first color filter is located inside the groove portion.
5 . The display device of claim 4 , wherein
the groove portion surrounds each of the first pixel aperture, the second pixel aperture, and the third pixel aperture.
6 . The display device of claim 1 , wherein
the third pixel apertures of the pixels extend along the first direction,
the first pixel apertures are aligned along a second direction that intersects the first direction of the third pixel apertures; and
the second pixel apertures are aligned along the second direction of the third pixel apertures and aligned along the first direction of the first pixel apertures.
