Liquid crystal display and liquid crystal display lower substrate assembly thereof

A liquid crystal display (LCD), comprising an LCD upper substrate assembly and an LCD lower substrate assembly, the LCD upper substrate assembly comprising a first carrier board and a first upper substrate arranged on the first carrier board, the LCD lower substrate assembly comprising a second carrier board, a first alignment pad, a first alignment wire, and first-group adaption pads having a function of electrical conduction, the first alignment pad, the first alignment wire, and the first-group adaption pads being all formed on the second carrier board, the first alignment pad being electrically connected to the first alignment wire in order to receive a first voltage signal and to apply the first voltage signal to the first alignment wire, the first-group adaption pads being electrically connected to the first alignment wire in a spaced manner to receive the first voltage signal and adapted to feed the first voltage signal to a first group of common electrodes arranged on a first upper substrate of the LCD upper substrate assembly, wherein connection portions between the first-group adaption pads and the first alignment wire and the first-group adaption pads are not crossing any other alignment wires on the second carrier board, except the first alignment wire,

• wherein the LCD lower substrate assembly further comprises a second alignment pad, a second alignment wire, and second-group adaption pads having a function of electric conduction, the second alignment pad, the second alignment wire, and the second-group adaption pads being all arranged on the second carrier board, the second alignment pad being electrically connected to the second alignment wire in order to receive the first voltage signal and to apply the first voltage signal to the second alignment wire, the second group second-group adaption pads being electrically connected to the second alignment wire in a spaced manner to receive the first voltage signal and adapted to feed the first voltage signal to a second group of common electrodes arranged on the first upper substrate of the LCD upper substrate assembly, wherein connection portions between the second-group adaption pads and the second alignment wire and the second-group adaption pads are not crossing any other alignment wires on the second carrier board, except the second alignment wire, and
• wherein the first alignment wire and the second alignment wire are arranged along a circumferential portion of the carrier board and every two successive ones of the adaption pads of the first and second groups of adaption pads are spaced by a constant distance so that the adaption pads of the first and second groups are uniformly distributed along the circumferential portion of the carrier board.
