一种像素单元及其制备方法、阵列基板和显示装置
摘要：
本发明提供了一种像素单元，所述像素单元包括：像素限定层、像素电极、发光层和公共电极，像素电极包括底面和侧面，侧面沿第二过孔的侧壁延伸至第二过孔侧壁的顶部，发光层形成于像素电极上，并将像素限定层覆盖，公共电极形成于发光层上，并将发光层覆盖并沿像素限定层顶面延伸。本发明的像素单元使得发光层向周围散射的光大为减少，像素单元之间的混色现象大为改善，有效地解决了光散射带来的混色问题，增大了像素单元的发光面积，提升了整体亮度，减少了掩膜成本并使整个工艺的成本大幅降低，提高了产能，提升了发光效果。
摘要（英）：

The invention provides a pixel unit.The pixel unit comprises a pixel limiting layer, a pixel electrode, a light-emitting layer and a common electrode.The pixel electrode comprises a bottom face and a side face, and the side face extends to the top of the sidewall of a second via hole along the sidewall of the second via hole.The light-emitting layer is formed on the pixel electrode and covers the pixel limiting layer, and the common electrode is formed on the light-emitting layer, covers the light-emitting layer and extends along the top face of the pixel limiting layer.The pixel unit enables the light-emitting layer to scatter much less light to the surrounding, so that color mixing among pixel units is improved greatly, the problem of color mixing caused by light scattering is solved effectively, light-emitting area of the pixel unit is increased greatly, overall brightness is enhanced, mask film cost is reduced to enable cost of the whole technology to be reduced substantially, production capacity is improved and light-emitting effect is improved.
