Embodiment 1

[0068] A color mosaic (color mosaic) CK-7001 (available from Fujifilm Co., Ltd.) is coated on a transparent substrate 1 (1737 glass produced by Corning Co., Ltd.), and a black matrix 2 having a plurality of rectangular openings is formed by photolithography. . Black matrix 2 has a film thickness of 1 μm. Each of the rectangular openings (corresponding to sub-pixels) has a length of 300 μm×a width of 100 μm, and the interval between adjacent rectangular openings is 30 μm in the length and 10 μm in the width.

[0069] Next, apply photocurable acrylate resin (V259PA / P5, produced by Nippon Steel Chemical Co., Ltd.), and use photolithography to form a pattern. On the black matrix 2, a bank 4 consisting of a plurality of strips extending in the longitudinal direction is formed. , the strip-shaped portions constituting the embankment 4 have a width of 10 μm and a height of 5 μm, respectively.

[0070] Next, at atmospheric pressure, in the ATOMFLO device (Surfx Technologies LLC prod...

Abstract

Disclosed is a simple process that can regulate the interaction between a color filter layer as a substrate and ink droplets for color conversion formation and can form a color conversion layer having a high-definition pattern. The process is characterized by comprising the steps of forming a plurality of types of color filter layers formed of polysiloxane and a pigment on a transparent substrate and a bank formed of a resin and provided at a boundary part between the dissimilar color filter layers to form a color filter, subjecting the color filter to oxygen plasma treatment, subjecting the color filter to fluorine plasma treatment, and forming a single type or a plurality of types of color conversion layers by an ink jet method on the color filter layers in the color filter.

Description

technical field [0001] The present invention relates to a method of manufacturing a color conversion filter. In particular, it relates to a method of manufacturing a color conversion filter including a color conversion layer having a high-precision pattern. Background technique [0002] As one of the methods of realizing multi-color light emission using organic EL elements, there is a color conversion method. The color conversion method is a method of realizing multi-color by disposing a color conversion layer on the front of the organic EL element. The color conversion layer absorbs light emitted by the organic EL element, converts the wavelength distribution, and emits light having a different wavelength distribution. Since the organic EL element used in the color conversion method is one type (monochrome), it is easy to manufacture, and development toward a large-screen display is being actively studied. In addition, the color conversion method has an advantageous featu...
