Those portions of the resin molding where the terminal portions are led out are dented from levels of portions around those portions. This provides a chip antenna which has a simple structure with a high mechanical strength and does not prevent separation or cracking from occurring in the resin molding in which the antenna element is buried and a method of manufacturing the chip antenna. so that the direction of line bisecting the angle which is made by the polarization axes of the polarizers substantially coincides with the average molecular long axis direction of the antiferroelectric liquid crystal in the absence of an applied voltage, and wherein in the reset period, the antiferroelectric liquid crystal is set to the first or second ferroelectric state.7.

The foregoing level shifters are current-driving-type level shifters that can operate even in the case where the transistor characteristics are inferior or in the case of fast operations, and that can carry out level shifting even with a start signal having a small amplitude. Furthermore, the foregoing level shifters are provided at both ends of the shift register section, respectively, and one of the same stops operating in accordance with a switching signal, so that consumed power should decrease. Consequently, there can be provided a shift register that is capable of shifting in two directions, that can normally operate even with an input signal having a small amplitude, and that therefore consumes less electric power.
