Abstract

The invention discloses a display panel. The display panel comprises an active region with pixels and a peripheral circuit region without pixels. A plurality of parallel data lines at intervals are arranged in the active region; fan-out leads used for connection with a driver chip are arranged in the peripheral circuit region; the active region is provided with first identifications, and the first identifications are formed at intervals on a plurality of ITO (indium tin oxide) layers of a thin film transistor array substrate by etching and used for distinguishing the data lines connected with the fan-out leads. By the first identifications arranged on the at least one ITO layer of the thin film transistor array substrate of the display panel, directly etching number identifications on metal grids in the prior art is replaced, quantity of the metal grids with etched number identifications is greatly decreased, each single metal data line on the display panel can be wider, and accordingly possibility of breakage of the metal data lines is reduced while ratio of rejects due to vertical lines generated on products is decreased. The invention further provides a display.

Description

technical field

[0001] The invention relates to the technical field of liquid crystal display, in particular to a display panel, a manufacturing method of the display panel and a display. Background technique

[0002] The liquid crystal display panel is composed of a color filter substrate with a color filter layer, a thin film transistor (TFT) array substrate and a liquid crystal layer arranged between the two substrates.

[0003] The current liquid crystal display panel is mainly based on the development trend of thin and light large screen, which requires a new generation of packaging technology with high density, small volume and free installation to meet the above requirements. Based on this, COF (Chip on Film, ie Chip-on-film) packaging technology emerged as the times require. This technology uses a flexible circuit board as a packaged chip carrier to bond the chip with the flexible substrate circuit. It is a grain soft film construction technology that fixes the drive...
