BARRIER WALL PATTERN FOR DISPLAY ELEMENT IN WHICH COLOR-SPECIFIC LIGHT-EMITTING BODY IS BURIED IN AT LEAST PART OF SUB-PIXEL, STRUCTURE, DISPLAY ELEMENT, AND METHOD FOR FORMING BARRIER WALL PATTERN

To provide a barrier wall pattern for a display element in which a color-specific light-emitting body is buried in at least a part of a sub-pixel, a structure having the barrier wall pattern, a display element having the structure, and a method for forming the barrier wall pattern which can suppress mixing of colors in sub-pixels due to stray light of blue light.SOLUTION: The present invention relates to a barrier wall pattern of a display element in which a color-specific light-emitting body is buried in at least a part of a sub-pixel, the barrier wall pattern including: a transparent substrate; a black matrix with an opening part patterned on the transparent substrate; and a barrier wall provided on the black matrix. Transmission when an optical wavelength of the barrier wall is 10 μm is 30% at largest when the wavelength is in a range of 440 nm to 470 nm, and is at least 50% when the wavelength is in a range of 520 nm to 700 nm.SELECTED DRAWING: None 【課題】青色光の迷光によるサブピクセル間の混色を抑制できる、サブピクセルの少なくとも一部に色別発光体が埋め込まれた表示素子の隔壁用パターン、該隔壁用パターンを備えた構造体、該構造体を備えた表示素子、及び隔壁用パターンの形成方法の提供。【解決手段】サブピクセルの少なくとも一部に色別発光体が埋め込まれた表示素子の隔壁用パターンであって、透明基板と、前記透明基板上にパターニングされた、開口部を有するブラックマトリクスと、前記ブラックマトリクス上に設けられた隔壁と、を備え、前記隔壁の光路長１０μｍにおける透過率が、波長４４０ｎｍ～４７０ｎｍの範囲において３０％以下であり、波長５２０ｎｍ～７００ｎｍの範囲において５０％以上である隔壁用パターン。【選択図】なし
