Abstract
An aspect of the present invention is a color filter for converting an incident light from one surface of the color filter to a light having a wavelength different from that of the incident light and permitting the converted light to exit from another surface of the color filter, the color filter comprising: a bank having a plurality of opening portions and being formed to extend from the another surface to the one surface of the color filter; a plurality of pixel portions formed in the respective opening portions; and a reflective film formed so as to cover at least part of the side of the bank.
Claims3
A color filter for converting an incident light from one surface of the color filter to a light having a wavelength different from that of the incident light and permitting the converted light to exit from another surface of the color filter,
- the color filter comprising:
- a bank having a plurality of opening portions and being formed to extend from the another surface to the one surface of the color filter;
- a plurality of pixel portions formed in the respective opening portions;
- and
- a reflective film formed so as to cover at least part of the side of the bank,
- the pixel portions having a pixel portion having a conversion layer containing light-emitting nanocrystalline particles,
- wherein the ratio of the height of the bank to the width of the bank is 0.5 or more, and
- wherein the angle between the side of the bank and the another surface of the color filter is 60 to 90°.
