Liquid Crystal Display Device Including Light Sources Emitting Different Colors

A display device comprising:

• a display panel including a first subpixel having a red color, a second subpixel having a green color and a transparent subpixel;
• and
• a light source part providing a light to the display panel and including a first light source configured to generate yellow light, and a second light source configured to generate blue light,
• wherein the second light source includes a blue light emitting diode, and a wavelength shift layer, and
• wherein the wavelength of the blue light emitted from the second light source has a first peak within a range of about 445 nm to about 450 nm and a second peak within a range of about 450 nm to about 540 nm.

A display device comprising:

• a set of transparent subpixels;
• and
• a light source part providing light to the set of transparent subpixels, the light source part including a first light source configured to generate red light, a second light source configured to generate green light and a third light source configured to generate blue light,
• wherein the third light source includes a blue light emitting diode and a wavelength shift layer configured to shift a wavelength of the blue light to a longer wavelength having a peak within a range of about 445 nm to about 450 inn and a second peak within a range of about 450 nm to about 540 nm.
