摘要： A driving base plate and a manufacturing method thereof, and a light emitting apparatus, which relates to the technical field of displaying. The driving base plate includes a functional region (A) and a peripheral region (B) surrounding the functional region (A). Both of the functional region (A) and the peripheral region (B) include a supporting substrate (1), and the functional region (A) further includes a flexible substrate (2) and at least one protecting layer that are sequentially arranged on the supporting substrate (1). The region of the orthographic projection of the flexible substrate (2) on the supporting substrate (1) is located within the region where the supporting substrate (1) within the functional region (A) is located, and the protecting layer covers the surface of the flexible substrate (2) that is further from the supporting substrate (1) and the side of the flexible substrate (2) close to the peripheral region (B). The adhesive force between the flexible substrate (2) and the supporting substrate (1) of the driving base plate is increased, and the reliability of the products manufactured by using the driving base plate is improved.

摘要： A light-emitting substrate and a display device. The light-emitting substrate (10) comprises a plurality of light-emitting units (100), a plurality of first voltage lines (21), and a plurality of first transmission lines (22). The plurality of light-emitting units (100) are arranged in an array of N ∗ M, and each of the plurality of light-emitting units (100) comprises a first voltage end (31). The plurality of first voltage lines (21) have one-to-one correspondence to multiple columns of light-emitting units (100). The first voltage line (21) comprises a first part (211), a first connecting portion (213), and a second part (212). The first part (211) is electrically connected to first voltage ends (31) of the first to Y-th rows of light-emitting units (100) of a corresponding column. The extension direction of the second part (212) of at least one first voltage line (21) has an angle with the first direction and the second direction, respectively. The first connecting portion (213) is located at the junction of the Y-th row of light-emitting units (100) and the (Y+1)-th row of light-emitting units (100). The plurality of first transmission lines (22) have one-to-one correspondence to multiple columns of light-emitting units (100). The first transmission lines (22) are electrically connected to first voltage ends (31) of the (Y+1)-th to N-th rows of light-emitting units (100) of the corresponding column, and are electrically connected to first connecting portions (213) of the first voltage lines (21) corresponding to the of light-emitting units (100) of the corresponding column. The light-emitting substrate (10) effectively reduces the width of a non-display area.
