Abstract: Embodiments of this application disclose a display panel. A primary pixel electrode is disposed inside a primary pixel region, and a sub-pixel electrode is disposed inside a sub-pixel region. First shading strips and second shading strips are intersected to form a plurality of primary frame bodies. One primary frame body correspondingly encloses a circumferential side of one pixel region. A third shading strip is disposed inside the primary frame body and correspondingly disposed between the primary pixel region and the sub-pixel region. The third shading strip and the primary frame body define two sub-frame bodies, and a channel for making the two sub-frame bodies communicate is disposed on the third shading strip.

Abstract: An embodiment of the present application discloses a pixel unit of a display panel and a display panel, wherein data lines are covered with a light shielding matrix element, two light shielding strips of the light shielding matrix element shield the two data lines respectively. Each light shielding strip comprises a first light shielding section and a second light shielding section in different widths overlap side edges of the main pixel electrode portion and side edges of the sub-pixel electrode portion respectively to effectively shield light leakage regions between the data lines and the pixel electrode, which solves the technical issue of the conventional pixel unit of a display panel forming light leakage regions between data lines and the pixel electrode, causing light leakage in a dark state, and resulting lowered display quality of the display panel and improves display quality.

Abstract: The present application discloses a pixel unit of a display panel, a lower substrate of a display panel, and a display panel. The present application by disposing a transparent shielding electrode element connected to a common signal line and extending into the aperture region and making an orthogonal projection of the transparent shielding electrode element on a plane where the common signal line is located at least partially overlap the common signal line, extends a shielding effect provided by the common signal line such that a parasitic capacitor between the pixel electrode and the data line is lowered.
