Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a color filter capable of preventing color mixture between adjacent pixels by thinning a color pixel and an overcoat and avoiding coating defects, such as keratin.SOLUTION: The color filter includes at least black matrixes, color pixels having a plurality of colors and an overcoat layer in this order on a transparent substrate. A taper angle between a superimposed part interface of the black matrix on the color pixel and the surface of the transparent substrate is 45° or more and 80° or less, and a ratio of the thickness of the color pixel to the thickness of the overcoat is one or mor and two or less. The color pixels have a pattern formed by a colored layer consisting of a photosensitive coloring composition including an organic color, a transparent resin, a monomer having an ethylenically unsaturated double bond and a photoinitiator. A ratio of the monomer having an ethylenically unsaturated double bond to the transparent resin is 0.5 or more and 0.7 or less.
【課題】着色画素とオーバーコートの薄膜化により隣接画素間の混色を防ぎ、且つ、ケラなどの塗布不良のないカラーフィルタを提供する。【解決手段】透明基板上に、少なくとも、ブラックマトリクスと、複数色の着色画素と、オーバーコート層をこの順で具備するカラーフィルタであって、前記ブラックマトリクスと前記着色画素との重畳部界面と、前記透明基板の面とのなすテーパー角度 が、45?以上80?以下であり、前記着色画素の膜厚、前記オーバーコートの膜厚の膜厚比率が、1以上2以下であり、前記着色画素が、有機顔料と、透明樹脂と、エチレン性不飽和二重結合を有するモノマーと、光重合開始剤とを含有した感光性着色組成物からなる着色層にてパターン形成された着色画素であって、前記エチレン性不飽和二重結合を有するモノマーと前記透明樹脂との比率が、0.5以上0.7以下である、ことを特徴とする。【選択図】図1 |
