摘要: A method of fabricating a display device may include the following steps: patterning a light blocking layer on a first surface of a first substrate, forming a color filter layer on a second surface of the first substrate opposite the first surface after the patterning of the light blocking layer, and forming a light conversion layer including a plurality of conversion filters on the first surface of the first substrate after the forming of the color filter layer. Each of the conversion filters may include a plurality of conversion particles, and the color filter layer may be formed to selectively transmit light emitted from each of the conversion filters.
