Abstract
The embodiment of the invention provides a display substrate, a preparation method thereof and a display device. The display substrate comprises a first metal layer, a first insulating layer, a first conductive layer, a second insulating layer and a second conductive layer which are sequentially arranged on one side of a substrate; the first metal layer comprises a plurality of data lines which extend in the second direction and are arranged in the first direction, the data lines are located between every two adjacent sub-pixel areas, and the second direction is not parallel to the first direction; the first conductive layer is in signal connection with a common electrode in the display substrate; the second conductive layer comprises a plurality of pixel electrodes, one pixel electrode is arranged in each sub-pixel area, the pixel electrodes are connected with second electrodes of the thin film transistors through first via holes, the first via holes penetrate through the second insulating layer and the first insulating layer, and the second insulating layer penetrates through the second insulating layer. The orthographic projection of the first via hole on the substrate is at least partially overlapped with the orthographic projection of the bearing electrode block on the substrate. According to the technical scheme, the lighting effect and the transmittance of the display substrate are improved.
Description
technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a display substrate, a preparation method thereof, and a display device. Background technique [0002] Liquid Crystal Displays (LCDs for short) have been widely popularized and gradually become mainstream products due to their small size, low power consumption, no radiation, and high display resolution. The LCD in the prior art has the problem of low light efficiency. SUMMARY OF THE INVENTION [0003] Embodiments of the present disclosure provide a display substrate, a method for manufacturing the same, and a display device to solve or alleviate one or more technical problems in the prior art. [0004] As a first aspect of the embodiments of the present disclosure, the embodiments of the present disclosure provide a display substrate, the display substrate includes a plurality of sub-pixel regions arranged in an array, and the display substrate includes: [000...
