Abstract: A column for defining the interval between a TFT substrate and an opposed substrate is formed at a crossing point between a drain line and a scanning line. At the crossing point where the column is formed, the drain line is formed to have a wider width to prevent light leakage. Further, at the crossing point where the column is formed, the scanning line is formed to have a narrower width to prevent increase of capacitance between the drain line and the scanning line. The column is formed at a crossing point corresponding to a specific color, e.g., a blue pixel B, so that a difference in transmittance and in characteristic of thin film transistors due to formation of the column is initially compensated.

Abstract: A bidirectional shift register capable of performing a stable shift operation in both directions and an image display device using the same are provided. In forward shift operation, when reference point N1 is at H level, (n+4)-th unit register circuit as a rear stage of the bidirectional shift register outputs pulse G(n+4) in synchronization with clock pulse V(n+4) inputted to (n+4)-th unit register circuit. A backward direction trigger signal VSTB is generated not only at the time of start of backward shift, but also, for example, in period (time t4 to t5) of one-phase clock immediately after G(n+4) is outputted in vertical blanking interval of the forward shift. The backward direction trigger signal VSTB is inputted to gate of a transistor provided to set reference point N1 of (n+4)-th unit register circuit to H level at the time of start of the backward shift.

Abstract: Second barrier electrodes are arranged under first barrier electrodes so as to fill gaps between the first barrier electrodes, while an insulating layer is located between the first barrier electrodes and the second barrier electrodes. The number of first barrier electrodes and the number of second barrier electrodes in each barrier pitch are 6 or more. The positions of the barriers formed by the first barrier electrodes and the second barrier electrodes are controlled by the reception of a signal representing detected positions of the eyes of a viewer. If pitches of the first barrier electrodes are defined as BE, and the widths of regions in which the first barrier electrodes are overlapped with the second barrier electrodes are defined as BA, a ratio BA/BE of the widths BA to the pitches BE are 0.3 or smaller. This configuration can suppress the occurrence of moire.
