1. A display device comprising:
a first substrate comprising a display area configured to emit a light having a predetermined peak wavelength from a plurality of light emitting areas and a non-display area surrounding the display area; and
a second substrate comprising a plurality of transparent areas overlapping the plurality of light emitting areas of the first substrate, the second substrate configured to convert the peak wavelength of the light or to transmit the light through the plurality of transparent areas,
wherein:
the second substrate comprises:
a base layer comprising the plurality of transparent areas, an inner light blocking area arranged between the plurality of transparent areas, and an outer light blocking area arranged outside the plurality of transparent areas;
a color filter disposed on the base layer; and
a light blocking layer disposed above the color filter and comprising an outer light blocking layer overlapping the outer light blocking area and an inner light blocking layer overlapping the inner light blocking area;
the inner light blocking layer comprises:
a first inner light blocking layer disposed above the color filter; and
a second inner light blocking layer disposed above the first inner light blocking layer;
the outer light blocking layer comprises:
a first outer light blocking layer disposed above the color filter and overlapping the outer light blocking area; and
a second outer light blocking layer disposed partially above the first outer light blocking layer and partially above the base layer to overlap the non-display area;
the second substrate further comprises:
a first capping layer covering the color filter in the display area and covering the base layer in the non-display area; and
a second capping layer disposed between the first inner light blocking layer and the second light blocking layer and between the first outer light blocking layer and the second outer light blocking layer;
a first distance between a top surface of the base layer and a top surface of the second outer light blocking layer is substantially the same as a second distance between a top surface of the base layer and a top surface of the second inner light blocking layer;
the second inner light blocking layer and the second outer light blocking layer are disposed directly on the second capping layer; and
a difference between the first distance and the second distance is within an error margin of about 3%.
