Abstract: PROBLEM TO BE SOLVED: To eliminate the influence of adhesives on the diffraction characteristics of a hologram by interposing a color tuning layer which widens or shifts the region of the diffraction wavelengths of a volume phase type hologram layer between a volume phase type hologram layer and an adherend at the time of adhering the latter to the former. SOLUTION: The back light side polarizing plate 47 of a liquid crystal display element 40 is adhered and integrated with a diffusion reflection type hologram by applying the adhesive 3 on the color tuning film 2 side of the diffusion reflection type hologram, by which a liquid crystal display device allowing a bright display without using a back light of spontaneous light emission type in a bright place is constituted. In such a case, the plasticizer, etc., in the adhesive 3 are used for color tuning and are blocked by the remaining color tuning film 2 and, therefore, the plasticizer, etc., hardly arrive at the hologram layer 1 and consequently, the diffraction characteristics of the hologram are not affected at all. As a result, the hologram layer 1 is capable of maintaining the as- designed stable diffraction characteristics.

IPC: H03H7/01
Filed: 1986-02-21
Abstract: PURPOSE:To realize a band pass filter without a small phase difference between the input and output by providing a band stop filter adding an output signal of a band pass filter to an input signal. CONSTITUTION:A signal from an input terminal 51 is added to an output of the band stop filter 53 by an adder means 52 and its added output is fed to the band pass filter 54, whose output signal is shared into an output terminal 56 and the band pass filter 53 by a distribution means 55. The pass band center frequency of the band pass filter 54 is selected identically as the stop center frequency of the band stop filter 53. Through the constitution above, the phase shift with respect to the input signal frequency is made flat near the center frequency. Thus, in using the band pass filter for a carrier recovery circuit in the PCM-TDMA communication, even when the frequency difference between burst signals is large, a recovered carrier with a small phase error is obtained.
