摘要：【中文】本发明提出了显示背板及其制作方法、显示装置。该显示背板包括：衬底，该衬底上限定有膜上芯片区；栅极，设置在衬底的一侧；绝缘层，设置在栅极远离衬底的一侧，且在膜上芯片区内具有第一开口；第一数据线，覆盖绝缘层，且通过第一开口与栅极接触；钝化层，覆盖第一数据线；第二数据线，设置在钝化层远离衬底的一侧且具有第二开口，并且，第一开口在衬底上的正投影落入第二开口在衬底上的正投影之内。本发明所提出的显示背板，其膜上芯片区的第一开孔处中的第二数据线可以被刻蚀出第二开口，从而避免第一开孔的斜坡处在后续阳极湿刻之后容易产生暗点，进而提升双源漏电极结构的显示背板的制作良品率。 【EN】The invention provides a display back plate, a manufacturing method thereof and a display device. The display backplane includes: a substrate having a chip-on-film region defined thereon; a gate disposed at one side of the substrate; the insulating layer is arranged on one side of the grid electrode, which is far away from the substrate, and a first opening is formed in the chip area on the film; a first data line covering the insulating layer and contacting the gate electrode through the first opening; a passivation layer covering the first data line; and the second data line is arranged on one side of the passivation layer away from the substrate and is provided with a second opening, and the orthographic projection of the first opening on the substrate falls into the orthographic projection of the second opening on the substrate. According to the display back plate provided by the invention, the second data line in the first opening of the chip area on the film can be etched to form the second opening, so that the situation that a slope of the first opening is easy to generate a dark spot after subsequent anode wet etching is avoided, and the manufacturing yield of the display back plate with the dual-source drain electrode structure is further improved.
