Display apparatus and method of manufacturing the same

A method of manufacturing a display apparatus, the method comprising:

• providing a base;
• forming a display layer on a side of the base, the display layer including a plurality of sub-pixels;
• forming a color filter layer on a display side of the display layer, the color filter layer including a plurality of color resistance portions in one-to-one correspondence with the plurality of sub-pixels, wherein a thickness of any color resistance portion is decreased and is stepwise changed at least twice in a direction away from a reference line of the color resistance portion, and the reference line is a straight line passing through a geometric center of the color resistance portion and perpendicular to the base;
• before the color filter layer is formed, the method of manufacturing the display apparatus further comprises:
• forming a first insulating layer, wherein a surface of the first insulating layer adjacent to the color filter layer is provided with a plurality of first grooves in one-to-one correspondence with the plurality of color resistance portions;
• a depth of any first groove is decreased in a direction away from a reference line of a corresponding color resistance portion;
• an orthographic projection of each color resistance portion on the display layer is located within a range of an orthographic projection of a corresponding first groove on the display layer;
• and a surface of each first groove adjacent to the color filter layer is in contact with a surface of the corresponding color resistance portion adjacent to the first insulating layer;
• and
• forming a black matrix provided with a plurality of openings, wherein the plurality of color resistance portions being in one-to-one correspondence with the plurality of openings;
• before forming the first insulating layer, the method of manufacturing the display apparatus further comprises:
• forming a touch structure layer, wherein the touch structure layer includes a plurality of electrodes, and orthographic projections of the plurality of electrodes of the touch structure layer on the display layer are located within a range of an orthographic projection of the black matrix on the display layer;
• wherein forming the touch structure layer, includes:
• forming a second insulating layer, bridges, first touch electrodes, and second touch electrodes, wherein
• the first touch electrodes and the second touch electrodes are insulated from each other and are arranged crosswise;
• each first touch electrode includes a plurality of first touch sub-electrodes separated by the second touch electrodes, and two adjacent first touch sub-electrodes of each first touch electrode are electrically connected through a bridge;
• and the bridges and the second touch electrodes are separated by the second insulating layer;
• and
• a surface of the second insulating layer adjacent to the first insulating layer is provided with a plurality of second grooves;
• the plurality of second grooves and the plurality of first grooves are in one-to-one correspondence, and an orthographic projection of each first groove on the display layer is located within a range of an orthographic projection of a corresponding second groove on the display layer;
• and a bottom surface of each second groove adjacent to the first insulating layer is in direct contact with a bottom surface of the first insulating layer adjacent to the second insulating layer.
