Patent ID: 7768188

Claim:
A display device comprising: a red cell; a green cell; and a blue cell, wherein each cell is arranged in a matrix in order to display an image and which output red light, green light, and blue light, respectively; and an optical filter provided uniformly on each of said cells and on the output side of light from said cells, wherein the penetrable rate of at least a portion of a wavelength band of light output from the green cell having the highest luminescent intensity is lower than the penetrable rates of wavelength bands of said red cell and said blue cell, wherein: in the green cell, the luminescent intensity is further increased in order to compensate for the amount of light that will run short when the penetrable rate of said optical filter is reduced, and the penetrable rate of the wavelength band of light emitted from said green cell in said optical filter is equal to or greater than 0.66 of the penetrable rate of the wavelength band of light emitted from said red cell and less than 1.
