40重量%，更佳為25 ~ 35重量%。在以上述範圍包括鹼溶性樹脂之情況下，可以形成圖案，且可以提高解析度及殘膜率。

When the color filter of the present invention is applied to an image display device, since light is emitted by the light of the light source of the display device, more excellent light efficiency can be achieved. In addition, since light having color is emitted, color reproducibility is more excellent, and since light is emitted in all directions by photoluminescence, a viewing angle can be improved. The color filter includes a substrate and a pattern layer formed on an upper portion of the substrate. As far as the substrate is concerned, the color filter itself may be a substrate, or may be a part where the color filter is located in a display device or the like, and there is no particular limitation.

The image display device of the present invention may include a color filter including a red pattern layer containing red quantum dot particles, a green pattern layer containing green quantum dot particles, and a blue pattern layer containing blue quantum dot particles. In this case, when applied to an image display device, the light emitted from the light source is not particularly limited, and in terms of more excellent color reproducibility, a light source that emits blue light is preferably used. According to another embodiment of the present invention, the image display device of the present invention may further include a color filter including only two color pattern layers among a red pattern layer, a green pattern layer, and a blue pattern layer. In this case, the color filter may further include a transparent pattern layer containing no quantum dot particles.
