Pixel structure utilizing photo spacer stage design and display device having the same

A pixel structure of a display device, comprising:

• (a) a plurality of pixels arranged in a matrix having L rows and N columns, wherein each of the plurality of pixels comprises K sub-pixels, L, N and K being integers greater than one, and the sub-pixels of each of the plurality of pixels comprise a plurality of first type sub-pixels and at least one second type sub-pixel, wherein:
• the sub-pixels are arranged along a row direction to form K*N columns of the sub-pixels;
• for each row of the matrix, the sub-pixels are arranged alternately such that each of the K*N columns of the sub-pixels comprises substantially the same numbers of the first type sub-pixels and substantially the same numbers of the second type sub-pixels;
• each of the sub-pixels has a color resist of a corresponding color, wherein the color resist of each of the first type sub-pixels has a first height, and the color resist of each of the second type sub-pixels has a second height;
• each of the first type sub-pixels and at least one of the second type sub-pixels respectively have a photo spacer disposed on the color resist;
• and
• for each of the plurality of pixels, the color resists of the second type sub-pixels have a sectional difference from the color resists of the first type sub-pixels, and the second height is greater than the first height;
• (b) at least K*N common voltage lines, each electrically connected to a corresponding column of the sub-pixels;
• wherein for each of the second type sub-pixels, a stage is extended from the corresponding common voltage line, and the color resist of each of the second type sub-pixels is disposed on the corresponding stage to form the sectional difference, such that each of the common voltage lines has substantially the same number of stages.

A pixel structure of a display device, comprising:

• a plurality of photo spacers;
• a first common voltage line elongating along an elongating direction, wherein a plurality of first stages extends from the first common voltage line, and each of the plurality of first stages elevates at least one of the plurality of photo spacer;
• and
• a second common voltage line elongating along the elongating direction located by the first common voltage line, wherein a plurality of second stages extends from the second common voltage line, and each of the plurality of second stages is not stacked under any of the plurality of photo spacers.
