Display panel, method for fabricating the same and display device

A method for fabricating a display panel, comprising steps of:

• forming a pattern of a data line on a first substrate;
• forming a protection layer on the data line, and forming a pattern of a second sub-via hole in a region of the protection layer which corresponding to the data line;
• sequentially forming patterns of a black matrix and a common electrode on the protection layer, and forming a pattern of a second via hole in the black matrix and the common electrode at a location corresponding to the second sub-via hole;
• forming a pattern of a conductive spacer in the second via hole, wherein a second end of the conductive spacer is connected to the data line by way of the second via hole, and the conductive spacer and the common electrode are disposed as insulating from each other, thereby forming a color filter substrate;
• forming an array substrate, wherein a gate electrode and a gate connection line of the array substrate are disposed orthogonal to each other, a first via hole is formed in a passivation layer of the array substrate in a region corresponding to the source electrode or the drain electrode;
• assembling the color filter substrate and the array substrate to form a cell, wherein a first end of the conductive spacer is connected to the source electrode or the drain electrode by way of the first via hole, and the gate connection line is disposed parallel to the data line.
