The liquid crystal panel includes an array substrate, a color filter substrate, and a cross-shaped spacer structure sandwiched between the array substrate and the color filter substrate. The cross-shaped spacer structure includes a plurality of H-shaped first spacers disposed on the upper surface of the array substrate and a plurality of strip-like second spacers disposed on the lower surface of the color filter substrate. The end surface of the crossbar of each one of the H-shaped first spacers and the end surface of each one of the strip-like second spacers are abutted against each other in a cross manner. Thus, when the liquid crystal panel is impacted by external force, the H-shaped first spacers and the strip-like second spacers can keep a tight abutment therebetween, so as to ensure the display quality of the liquid crystal panel.

Abstract: PROBLEMSTo provide a method for evaluating characteristics of MZ interferometers in an optical modulator having a plurality of MZ interferometers.MEANS FOR SOLVING PROBLEMSWhen an optical modulator includes a plurality of MZ interferometers, the 0-degree component contains a signal derived from an MZ interferometer other than the MZ interferometers for evaluating the characteristic. For this, it is impossible to accurately evaluate the characteristic of the MZ interferometers. The present invention does not use the 0-degree component normally having the highest intensity. That is, the characteristic of the MZ interferometers are evaluated by using a side band intensity of the component other than the 0-degree component.

Abstract: The optical modulator includes optical modulation units. The plurality of optical modulation units is disposed in parallel on the same substrate. One input waveguide branches off to be connected to the Mach-Zehnder type optical waveguide of each optical modulation unit, and an entire optical waveguide is formed such that outputs from the Mach-Zehnder type optical waveguides are combined and output through one output waveguide. A modulation signal with the same intensity is applied to a modulation electrode of each optical modulation unit. In at least some of the optical modulation units, mechanical structures including the modulation electrodes of the optical modulation units are configured such that an amplitude value of an optical output modulated by the modulation signal of the optical modulation unit is ½n (n is a natural number) of a maximum amplitude value in other optical modulation units.
