    Abstract: A display device includes a via-insulating layer defining a trench including a substantially inclined surface and a substantially flat surface, a light emitting layer on the via-insulating layer and including a first portion parallel to the substantially inclined surface and a second portion disposed parallel to the substantially flat surface, and a color conversion layer on the light emitting layer. A first angle formed between a first imaginary straight line, which connects a point where the first portion and the second portion meet and an edge of the color conversion layer and forms an obtuse angle with the first portion, and a second imaginary straight line, which extends perpendicular to the first portion, is greater than a second angle formed between a travel direction of a light having a greatest luminous intensity among lights emitted from the first portion and the second imaginary straight line.

    Abstract: A mother substrate for a color conversion substrate includes: a substrate including a display area and a tag area, where the tag area is disposed around the display area and includes a plurality of sub-tag areas; a first ink layer disposed in some of the sub-tag areas and having a first color; and a second ink layer disposed in some of the sub-tag areas and having a second color different from the first color. A volume of the first ink layer in each of the some of the sub-tag areas is different from each other, or a volume of the second ink layer in each of the some of the sub-tag areas is different from each other.

    Abstract: A display device includes a color conversion pattern including first red quantum dots, a color reinforcement pattern adjacent to the color conversion pattern and including second red quantum dots, and an emission layer disposed on the color reinforcement pattern. A concentration of the second red quantum dots in the color reinforcement pattern is less than a concentration of the first red quantum dots in the color conversion pattern.
