摘要： A display apparatus includes a light-source substrate portion which generates light; and a color control portion to which the generated light from the light-source substrate portion is incident and at which color of the generated light is adjusted to define a color-converted light having a color different from that of the generated light. The color control portion includes: an exit surface through which the color-converted light exits the color control portion; a substrate including a plurality of concave portions defined therein, each of the concave portions extended along a direction from the light-source substrate portion to the exit surface of the color control portion; and a plurality of color conversion members respectively in the plurality of concave portions, the color conversion members each including a color-converting material which converts the color of the generated light to the color of the color-converted light.
