Display device and composition for forming bank

The invention relates to a display device and a composition for forming a bank. A display apparatus includes: a substrate on which a plurality of light emitting devices are located; a plurality of color conversion layers on the substrate and corresponding to the plurality of light emitting devices; and a plurality of banks between the plurality of color conversion layers, where each of the plurality of banks includes first scattering particles, second scattering particles, and a pigment, and an average diameter (D50) of the first scattering particles and an average diameter (D50) of the second scattering particles differ from each other, and the average diameter of the first scattering particles is at least about 150 nm and at most (e.g., no greater than) about 200 nm. 本申请涉及显示设备以及用于形成堤的组合物。显示设备，包括：衬底，多个发光器件位于衬底上；多个颜色转换层，在衬底上并且与多个发光器件对应；以及多个堤，在多个颜色转换层之间，其中，多个堤中的每一个包括第一散射颗粒、第二散射颗粒和颜料，并且第一散射颗粒的平均直径(D50)和第二散射颗粒的平均直径(D50)彼此不同，并且第一散射颗粒的平均直径为至少约150nm并且至多(例如，不大于)约200nm。
