Pixel structure comprising a pixel electrode having block-shaped portion and branch-shaped portion formed over a passivation layer having branch-shaped portion and block-shaped portion

A pixel structure comprising:

• a substrate;
• an opposite substrate disposed on the substrate, the opposite substrate having a common electrode on one side of the opposite substrate facing the substrate;
• a scan line and a data line both formed on the substrate;
• an active device formed on the substrate and electrically connected to the scan line and the data line;
• a pixel electrode electrically connected to the active device, the pixel electrode having at least one block-shaped electrode and a plurality of first branch electrodes;
• and
• a passivation layer located below the pixel electrode, the passivation layer having at least one block-shaped protrusion pattern, a plurality of branch protrusion patterns, and a plurality of grooves,
• wherein the at least one block-shaped electrode of the pixel electrode conformally covers the branch protrusion patterns of the passivation layer, such that the at least one block-shaped electrode protrudes based on the branch protrusion patterns to form a plurality of second branch electrodes,
• wherein the first branch electrodes of the pixel electrode are located on the at least one block-shaped protrusion pattern of the passivation layer,
• wherein an edge of the at least one block-shaped electrode of the pixel electrode further extends to the at least one block-shaped protrusion pattern of the passivation layer,
• wherein an orthogonal projection gap W1 is between an orthogonal projection edge of the at least one block-shaped electrode and an orthogonal projection edge of a nearest one of the first branch electrodes, and 0 μm<W1≦4 μm, and
• wherein an orthogonal projection distance W2 is between the orthogonal projection edge of the at least one block-shaped electrode and an orthogonal projection edge of the at least one block-shaped protrusion pattern, and 2 μm≦W2≦5.5 μm.
