Technical Problem
对于大尺寸显示面板，像素区域尺寸较大，封装体容易装配且相互之间不互相干涉；但小尺寸显示面板的像素区域的尺寸很小，封装体难以装配，该方式难以应用于高分辨率的应用场景
Benefits of technology
[0045]本申请实施例所提供的显示装置，通过在包括多个发光单元的芯片层上设置包括多个驱动单元的驱动层，并使得发光单元和驱动单元导电连接，由此实现了发光单元的有源驱动，并且发光单元和驱动单元在竖直方向上集成，有利于提高集成化程度，以适用超高分辨率微显示；通过在生长了多个发光单元的生长衬底上直接集成驱动单元，实现单片集成，规避了多个发光单元巨量转移的混合集成，带来的工艺难度高、效率低、良率损失大的问题；生长衬底除了可以提供机械支撑，还可以形成像素槽和硅墙，有利于降低发光单元间的光学串扰。

Abstract
Embodiments of the present application relate to a display device, comprising: a growth substrate comprising a first surface and a second surface opposite to each other, a material of the growth substrate being silicon; a chip layer formed by epitaxial growth on the first surface of the growth substrate, comprising a first semiconductor layer, an active layer and a second semiconductor layer stacked in sequence in a direction away from the growth substrate, the chip layer comprising a plurality of light emitting units; a driving layer located on a side of the chip layer away from the growth substrate, comprising a plurality of driving units, the driving units being in conductive connection with the light emitting units; and a pixel groove located in the growth substrate, extending in a direction from the second surface to the chip layer, and corresponding to positions of the light emitting units. Thus, active driving of the light emitting units is better achieved.
