Abstract

A display panel (PNL) and a display apparatus, which relate to the technical field of display. The display panel (PNL) comprises a base substrate (SBT), a driving layer (DRL) and a pixel layer (PIXL), which are sequentially stacked, wherein the driving layer (DRL) has transistors (TFTs) for driving sub-pixels (PIX); at least one transistor (TFT) comprises a channel region (CR) located on a semiconductor layer (SCL), and comprises two conductive structures (CSs) located on two sides of the channel region (CR); at least one conductive structure (CS) comprises an electrical contact structure (ECS) located on the semiconductor layer (SCL), an overlapping insulation structure (GIS) located on a gate insulation layer (GI), and an overlapping structure (OS) located on a second metal layer (GT); the overlapping insulation structure (GIS) has an overlapping via hole (GIH), and the overlapping structure (OS) is electrically connected to the electrical contact structure (ECS) by means of the overlapping via hole (GIH); and the length direction (ED) of at least one overlapping via hole (GIH) of the at least one transistor (TFT) is not parallel to the length direction (LE) of the channel region (CR) of the transistor (TFT). The display panel (PNL) can improve the space utilization rate to the greatest extent, improve the aperture ratio of a display device, and prolong the service life of an OLED device.
