LIGHT-DIFFUSING MEMBER, METHOD FOR MANUFACTURING LIGHT-DIFFUSING MEMBER, AND DISPLAY DEVICE |
摘要 |
This light-diffusing member includes a light-transmissive substrate, a plurality of wavelength-controlling layers formed on one surface of the light-transmissive substrate, and a light-diffusing portion formed on the one surface of the light-transmissive substrate in a region other than a region where the wavelength-controlling layers are formed. The light-diffusing portion includes a light-emitting end-surface that makes contact with the light-transmissive substrate and a light-incident end-surface that is opposite to the light-emitting end-surface and that has an area greater than an area of the light-emitting end-surface, and is made of a photosensitive resin; a height of the light-diffusing portion from the light-incident end-surface to the light-emitting end-surface is greater than a thickness of the wavelength-controlling layers; and the wavelength-controlling layers have characteristics that an optical absorptance at a first wavelength in a ultraviolet wavelength band is higher than an optical absorptance at a second wavelength in a visible-light wavelength band. |

1. A light-diffusing member, comprising:
a light-transmissive substrate; a plurality of wavelength-controlling layers formed on one surface of the light-transmissive substrate; and a light-diffusing portion which is provided on the one surface of the light-transmissive substrate; the wavelength-controlling layers which are provided in a region other than formation region of the light-diffusing portion, wherein the light-diffusing portion includes a light-emitting end-surface that makes contact with the one surface of the light-transmissive substrate and a light-incident end-surface that is opposite to the light-emitting end-surface and that has an area greater than an area of the light-emitting end-surface, and is made of a photosensitive resin and, wherein a height of the light-diffusing portion from the light-incident end-surface to the light-emitting end-surface is greater than a thickness of the plurality of wavelength-controlling layers, and wherein the plurality of wavelength-controlling layers have characteristics that an optical absorptance at a first wavelength in an ultraviolet wavelength band is higher than an optical absorptance at a second wavelength in a visible-light wavelength band. |
