Color filter substrate and method of manufacturing the same, and display device

A method of manufacturing a color filter substrate, comprising the following steps of:

• providing a first glass substrate and forming a pattern of a common electrode layer on a surface of the first glass substrate;
• providing a second glass substrate and forming a pattern of a color filter layer on a first surface of the second glass substrate, said color filter layer comprising a plurality of color filters with a void region therebetween;
• forming a pattern of a plurality of pixel electrodes spaced from one another on a second surface of the second glass substrate opposite from the first surface such that a projection of the pattern of said plurality of pixel electrodes in a plane where said second surface is located is within a projection of the void region in the plane;
• and
• forming, after forming the pattern of the plurality of pixel electrodes, a transparent photoresist pattern on the second surface of the second glass substrate, wherein said transparent photoresist pattern includes a plurality of transparent photoresist elements and a groove region between said plurality of transparent photoresist elements, a projection of each transparent photoresist element in the plane is overlapped with that of a corresponding color filter in the plane, and, a projection of the groove region in the plane is within or is fully overlapped with a projection of said void region in the plane;
• filling, after forming the transparent photoresist pattern, said groove region with electronic ink;
• and
• assembling, after filling of the electronic ink, the first glass substrate and the second glass substrate in such a manner that the surface of the first glass substrate formed with the common electrode layer seals and covers the electronic ink on the second glass substrate.
