Abstract

The invention discloses a display panel. The display panel comprises a substrate, a first light shield layer arranged on the substrate, a semiconductor layer arranged on the first light shield layer, an insulation layer arranged on the semiconductor layer, a grid line arranged on the insulation layer, a contact hole penetrating through the insulation layer to expose the semiconductor layer, and a metal layer which is arranged on the insulation layer and is electrically connected with the semiconductor layer through the contact hole, wherein the first light shield layer comprises an overlapping area, the overlapping area and the metal layer are overlapped mutually, the overlapping area has first width in the first direction, the shortest distance in the first direction between one edge of the metal layer close to the grid line and a bottom portion of the contact hole is second width, the first direction is actually perpendicular to an extension direction of the grid line, and the ratio of the first width to the second width is in a range of 0.2-0.8.

Description

technical field [0001] The present invention relates to a display technology, and in particular to a pixel unit for a display panel. Background technique [0002] Display devices (for example, liquid crystal display (liquid crystal display, LCD), active matrix organic light-emitting display (active matrix organic light-emitting display, AMOLED), etc. are usually assembled in electronic devices, such as laptop computers, personal digital assistants (personal digital assistants) digital assistants, PDA), e-books (electronic books), projectors, and mobile phones, etc. [0003] In general, a display panel usually uses thin film transistors (thin film transistors, TFTs) as switching elements in pixel regions. Furthermore, the peripheral circuit area (that is, the driving circuit area) also needs to use a CMOS circuit composed of TFTs. According to the materials used in the active layer, TFTs are classified into amorphous silicon (a-Si) and polysilicon (poly-Si) TFTs. Compared ...
