Abstract

(EN) The present application relates to a display panel, a method for manufacturing a display panel, and a display apparatus. The display panel comprises a deformation layer, which is sandwiched between a pixel definition layer and a hole injection layer of the display panel, wherein the deformation layer is used for disconnecting the hole injection layer from a hole transport layer of the display panel during a manufacturing process of the display panel, thereby preventing holes from flowing laterally to form a lateral leakage current, and improving the pixel luminescence purity and thus improving a display effect.

(FR) La présente invention concerne un panneau d'affichage, un procédé de fabrication d'un panneau d'affichage, et un appareil d'affichage. Le panneau d'affichage comprend une couche de déformation, qui est prise en sandwich entre une couche de définition de pixels et une couche d'injection de trous du panneau d'affichage, la couche de déformation étant utilisée pour déconnecter la couche d'injection de trous d'une couche de transport de trous du panneau d'affichage pendant un processus de fabrication du panneau d'affichage, ce qui permet d'empêcher des trous de s'écouler latéralement pour former un courant de fuite latéral, et d'améliorer la pureté de luminescence de pixel et d'améliorer ainsi un effet d'affichage.

(ZH) 本申请涉及一种显示面板、显示面板制作方法和显示装置，所述显示面板，包括夹设在显示面板的像素定义层和空穴注入层之间的形变层；形变层用于在显示面板的制作过程中，断开显示面板的空穴注入层和空穴传输层，从而阻止空穴横向流动形成横向的泄漏电流，提高了像素发光的纯度，提高了显示效果。
