DISPLAY

摘要

A display characterized in that it comprises a selective reflecting layer (SR) provided between a quarter- wave plate (WP) and a light-emitting layer (64), containing liquid crystal molecules aligned at predetermined helical pitches, transmitting a first circularly polarized light, and selectively reflecting a second circularly polarized light having a polarity opposite to that of the first circularly polarized light and a predetermined wavelength, the light-emitting layer (64) has at least one peak wavelength, the selective reflecting layer (SR) has m selective reflection wavelength regions when the number of peak wavelengths of the light-emitting layer (64) is m, the peak wavelength lambdap(k) of the light emitted from the light-emitting layer (64) (where k=1, 2,..., m in the descending order of wavelength) is smaller than the product ne(k)P(k) of the extraordinary light refractive index ne(k) of the selective reflecting layer (SR) constituting the selective reflection wavelength regions and the helical pitch P(k) and larger than the product no(k)P(k) of the ordinary light reflective index no(k) and the helical pitch P(k), and the condition ne(k- 1)P(k-1)
