Definitions
- the present invention relates to a color light-emitting device, and more particularly to a color light-emitting device using an organic electroluminescent device (hereinafter, referred to as an organic EL device) suitable for a color display.
- an organic electroluminescent device hereinafter, referred to as an organic EL device
- blue, green, and red light emitting elements are arranged on a screen.
- the life of the pixels corresponding to the three colors is different.
- the life and efficiency of the red light-emitting material are low, so it was difficult to obtain a light-emitting device with high efficiency and a small white balance over time. .
- blue, green, and red colors are extracted from white light, which contains all three primary colors, using a color filter.
- the “color filter” is a filter that blocks a part of the light emitting component of the organic EL device and transmits only a desired light emitting component.
- the device configuration becomes very complicated, and it has been difficult to produce a device with good reproducibility.
- FIG. 16 is a schematic diagram of a color light emitting device using a conventional color conversion method.
- 10 is a color light-emitting device
- 12 is a blue pixel
- 14 is a green pixel
- 16 is a red pixel
- 20 is an organic EL element that emits blue light
- 30 contains a fluorescent dye.
- 2 shows a color conversion member.
- the fluorescent dye is excited when irradiated with light having a predetermined wavelength, and converts the light into fluorescent light having a longer wavelength.
- the color conversion member 30 includes a green conversion member 34 and a red conversion member 36.
- the green conversion member 34 converts blue light emitted from the organic EL element 20 into green light
- the red conversion member 36 converts blue light into red light. That is, the blue light emitted from the organic EL element 20 is partially converted into green light and red light by the color conversion member 30, thereby obtaining pixels that emit blue, green, and red primary colors.
- a color light emitting device is formed.
- the energy difference is large for converting blue light to red light, and the conversion efficiency is lower than that for converting blue light to green light. That is, there is a problem that the intensity of red light is lower than the intensity of blue light and green light.
- Japanese Patent Application Laid-Open No. H10-037971 discloses that the area ratios of the red, blue, and green color pixels are made different from each other.
- the area ratio of the red pixels is increased to increase the intensity of the red light. That is, a technique for increasing the red luminance and maintaining the white balance for a long time is described.
- this technique since the area ratio of each color pixel is different from each other, the arrangement pattern of pixels becomes complicated.
- the red conversion member is made by dispersing a fluorescent dye that emits red fluorescence by absorbing the light-emitting component of the organic EL element in a transparent binder material.
- a fluorescent dye that emits red fluorescence by absorbing the light-emitting component of the organic EL element in a transparent binder material.
- the red conversion member deteriorated, affecting the color stability of the entire light emitting device.
- a color filter that removes unnecessary light-emitting components, which degrades color purity, is useful. Since both the luminous efficiency and the conversion efficiency of the color conversion member are limited, if unnecessary light is removed with a color filter to improve the color purity, the luminous efficiency of the color light emitting device must be extremely low.
- the present invention has been made in view of the above circumstances, and it is an object of the present invention to increase the intensity of red light without making pixel area ratios different from each other, and suppressing the uneven bias of organic EL elements. It is an object of the present invention to provide a color light-emitting device capable of performing the above-mentioned.
- Another object of the present invention is to provide a color light emitting device which has good color purity and luminous efficiency and has a long life.
- the present inventors have conducted intensive studies and found that the intensity of red light can be increased by matching the peak of the emission spectrum of the organic EL element with the peak of the excitation spectrum of the red conversion member.
- the present invention has been completed.
- the present inventors have proposed a color light emitting device by combining a light emitting element that emits light having a blue component and a yellow to red component with an emission intensity ratio of 9: 1 to 5: 5 and a color conversion member.

- a light emitting device is provided which coincides with the peak outside region III.
- the coincidence means that the wavelengths of the peaks, which are the maximum values of the spectrum curve, almost coincide with each other. —That is, the difference between the peak wavelengths is within 10 nm, preferably within 5 nm.
- the peak of the emission spectrum of the organic EL element is matched with the peak of the excitation spectrum of the color conversion member of the red pixel, which contributes to the emission of the red conversion member.
- the ratio of the number of effective photons to be used can be increased. As a result, the emission intensity of the red pixel, that is, the luminance can be improved.
- the red intensity can be increased even when a uniform drive voltage is applied to each color pixel. Furthermore, it is possible to suppress unbalanced deterioration of the organic EL element and maintain high red intensity for a long time. In addition, it is possible to extend the luminance of the color light emitting device without complicating the pixel pattern.
- each color filter blocks unnecessary color components, thereby improving the reproducibility of each color.
- the ratio of the peak intensity in the blue region to the peak intensity in the region other than the blue region of the emission spectrum is 9: 1 to 5: 5.
- the red light emission intensity may decrease, and it may not be possible to maintain the white balance of the color light emitting device.
- the peak intensity ratio is less than 5: 5
- the red light emission intensity is large, but the light emission intensity of the blue pixel is relatively small, so that it may not be possible to secure the white balance of the color light emitting device. is there.
- the peak intensity ratio is in the range of 9 ::! To 5: 5
