Abstract

Provided are a display panel and a manufacturing method thereof, a display device and a spliced display device. The display panel includes: a color filter substrate (11), an array substrate (12) and a first conductive portion (13), where a display region (AA) and a peripheral region (NA) are formed on the display panel, and the peripheral region (NA) surrounds the display region (AA); the array substrate (12) includes pixel circuits and a second conductive portion (14), where the pixel circuits are located in the display region (AA), and the second conductive portion (14) is located in the peripheral region (NA); the second conductive portion (14) is connected with the pixel circuits; the first conductive portion (13) is located on a side surface of the array substrate (12) and a side surface of the color filter substrate (11), and the first conductive portion (13) is connected with the second conductive portion (14). By such technical solutions, a width of the peripheral region can be reduced, which is beneficial to realizing a narrow bezel and increasing a screen-to-body ratio.
