The present invention provides a display panel comprising an array substrate and a counter substrate. The array substrate includes a first substrate, a first signal line and a second signal line provided on the first substrate, and a first transmission pad provided in a peripheral region of the first substrate. A second transfer pad provided on a peripheral region of the second substrate, a common electrode provided on the light blocking layer, and a first alignment film provided on the common electrode. The second transfer pad is electrically connected to the first transfer pad and the common electrode. The light blocking layer at least partially corresponds to the first signal line and the second signal line, wherein the light shielding layer comprises a unit light shielding portion having a slit. The first alignment film is disposed in the slit. The unit shading portion is adjacent to a boundary of the display area of the second substrate and corresponds to the second transfer pad.
