Abstract

The present invention provides a display panel and a display device. The display panel includes a light emitting unit arranged on an array substrate and a thin film encapsulation layer on the light emitting unit, and also includes: a plurality of light filters arranged on the thin film encapsulation layer layer and a black matrix for separating the filter layer, wherein the side of the black matrix has a plurality of steps, and the plurality of steps are arranged obliquely outward from the bottom end to the top end of the black matrix , so that the incident light irradiated on the step is scattered. The display panel provided by the present invention effectively increases the scattering of external incident light and reduces the direct reflection of incident light, thereby reducing the outgoing amount of reflected light, further reducing the reflectivity of external ambient light, and making the display effect of the display panel Even better, it solves the problem that the display effect of the display panel is greatly affected due to the high reflectivity of external ambient light in the existing panel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Display screens have been widely used in many fields such as portable electronic devices (such as mobile communication terminals, tablet computers, e-books, and navigation equipment) and large-screen electronic devices. Among them, organic light-emitting diodes (Organic Light-Emitting Diode, referred to as : OLED) has been gradually applied to display screens due to its low power consumption, high color saturation, wide viewing angle, thin thickness, and flexibility. [0003] At present, in OLED displays, BM-CF technology is used to form a color filter (ColorFilter, referred to as: CF) and a black matrix (Black Matrix, referred to as: BM) on the thin film encapsulation layer to replace the circular polarizer (because the polarizer and Thick and hard), wherein, the black matrix is ​​used as a color-defin...
