Abstract: The present invention discloses an evaporation method and an evaporation device. The evaporation method includes successively providing at least one mask above a base substrate and forming at least one evaporation sub-pattern on the base substrate by an evaporation process so that an evaporation pattern is formed on the base substrate, wherein the evaporation pattern is constituted by the at least one evaporation sub-pattern. As the evaporation pattern finally formed is constituted by the at least one evaporation sub-pattern, only a small number of opening regions are required to be formed on each of the masks used for forming the evaporation sub-patterns compared with the prior art, so that the widths of the shield regions between the adjacent opening regions may be set to be larger.

Abstract: An array substrate includes a substrate and data lines and scan lines arranged on the substrate. The data lines and the scan lines define plural pixel regions. A thin film transistor is arranged in each pixel region and includes a gate electrode, a source electrode, a drain electrode, and an active region. The gate electrode is arranged above the active region. The source electrode and the drain electrode are arranged at two opposite sides of the active region respectively. A light shielding metal layer is further arranged in each pixel region. The light shielding metal layer and the data lines are arranged in the same layer on the substrate. The light shielding metal layer is arranged under the active region and at least partially overlaps with the active region. The data line is close to the source electrode and does not overlap with the active region at least partially.
