Backlight assembly, display apparatus having the same and method of manufacturing the same

A display apparatus comprising:

• a display panel comprising a first subpixel configured to display a first primary color, a second subpixel configured to display a second primary color, and a transparent subpixel;
• a backlight assembly configured to provide light to the display panel, the backlight assembly comprising:
• a first light source part comprising a plurality of first light sources configured to generate light having a first color, and a plurality of second light sources configured to generate light having a second color different from the first color, the first and second light sources being alternately located, the first color being a mixed color comprising the first primary color and the second primary color, the second color being the second primary color;
• and
• a light guiding plate comprising a first incident surface and an exiting surface adjacent to the first incident surface, the exiting surface comprising a first peripheral portion configured to partially absorb the light having the second color and a central portion adjacent to the first peripheral portion and configured to allow the light to pass therethrough;
• and
• a receiving container accommodating the display panel and the backlight assembly.

A method of manufacturing a backlight assembly comprising:

• forming a first light source part, the first light source part comprising a plurality of first light sources configured to generate light having a first color, and a plurality of second light sources configured to generate light having a second color different from the first color, the first and second light sources being alternately located;
• and
• forming a light guiding plate, the light guiding plate comprising a first incident surface and an exiting surface adjacent to the first incident surface configured to allow the light to pass therethrough, and a reflecting surface opposite to the exiting surface,
• wherein forming the light guiding plate comprises:
• forming a light exiting pattern on the exiting surface;
• and
• forming first and second absorbing patterns by depositing ink on the exiting surface through a mask, the mask comprising a first portion having a plurality of openings, a second portion spaced from the first portion and having a plurality of openings, and a third portion between the first portion and the second portion, the ink configured to absorb light having a wavelength within a range.
