Abstract

A capacitive light emitting device panel having a plurality of pixels each of which is constructed by a red light emitting unit, a green light emitting unit, and a blue light emitting unit. A ratio of areas of light emitting surfaces of the red light emitting unit, green light emitting unit, and blue light emitting unit is set so that voltage differences among peak voltages of applied voltages to the red light emitting unit, green light emitting unit, and blue light emitting unit lie within a predetermined voltage range.

Claims

1. A capacitive light emitting device panel having a plurality of pixels each of which is constructed by a red light emitting unit, a green light emitting unit, and a blue light emitting unit, wherein

a ratio of areas of light emitting surfaces of said red light emitting unit, said green light emitting unit, and said blue light emitting unit is set so that voltage differences among peak voltages of applied voltages to said red light emitting unit, said green light emitting unit, and said blue light emitting unit lie within a predetermined voltage range.

2. A panel according to claim 1, wherein the area of the light emitting surface of said blue light emitting unit is the smallest.

3. A panel according to claim 1, wherein the area of the light emitting surface of said red light emitting unit is the largest.
