Array base plate, display panel and display device

Abstract

The invention provides an array base plate. The array base plate comprises a under-laying base plate, a gate graphics layer, a source graphics layer and a source drain graphics layer, the gate graphics layer comprises multiple stripes of gate lines, the source drain graphics layer comprises multiple stripes of data lines, the gate lines and the data lines are arranged alternately, the array base plate is divided into multiple pixel units, the array base plate comprises a thin-film transistor arranged in the pixel units, the gate graphics layer comprises further a grid electrode of the thin film transistor, the source drain graphics layer comprises a source electrode and a drain electrode of the thin film transistor, the source graphics layer comprises an active layer of the thin-film transistor, wherein the orthographic projection of the drain electrode of the thin-film transistor on the under-laying base plate does not exceed the orthographic projection of the gate electrode of the thin film transistor on the under-laying base plate. The invention also provides a display panel and a display device. Poor display quality is not easily arisen by the display panel when displaying is conducted.
