Definitions
- a horizontal electric field mode including an IPS mode and an FFS mode
- a vertical alignment mode VA mode
- the VA mode is more mass-productive than the horizontal electric field mode, it is widely used for TV applications and mobile applications.
- the MVA mode is most widely used.
- the MVA mode is disclosed in Patent Document 1, for example.
- Patent Documents 3 to 7 disclose configurations using pixel electrodes having a fine stripe pattern together with the PSA technique.
- this configuration when a voltage is applied to the liquid crystal layer, the liquid crystal molecules are aligned parallel to the longitudinal direction of the stripe pattern.
- This is in contrast to the conventional MVA mode described in Patent Document 1 in which liquid crystal molecules are aligned in a direction perpendicular to a linear alignment regulating structure such as a slit or a rib.
- the line and space of the fine stripe pattern (hereinafter sometimes referred to as “comb-like fine electrode structure”) may be smaller than the width of the conventional MVA mode orientation regulating means. Therefore, the comb-like fine electrode structure has an advantage that it can be easily applied to a small pixel as compared with the conventional MVA mode orientation regulating means.
- FIG. 12 shows a conventional liquid crystal display device 500 including a pixel electrode 512 having a comb-like fine electrode structure.

Therefore, the pretilt azimuth of the liquid crystal molecules 3a defined by the alignment maintaining layers 34a and 34b (the direction in which the liquid crystal molecules 3a tilt when no voltage is applied) matches the direction in which the liquid crystal molecules 3a tilt when a voltage is applied. .
