Title: Liquid crystal display device
Inventor: NAKAJIMA TAKESHI
IPC: H01L29/786
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal display device having a horizontal electric field system, a wide angle of visibility and good display characteristics and easily producible at a low cost by decreasing defects called as load traces which are display defects caused by loading on the display face and which are recognized for a long time even after the load is removed. SOLUTION: The top ends of a pixel electrode 10 and a counter electrode 11 are provided with bends 10a and 11a bent in the opposite direction to the alignment direction of a liquid crystal to a source wiring 12. The angle θe of the bends 10a and 11a from the source wiring 12 satisfies 1 deg.<θe<90 deg.. Thus, the direction of the electric field at the top ends of the pixel electrode 10 and the counter electrode 11 can be controlled to the direction where the liquid crystal is required to rotate, and the liquid crystal rotating in the opposite direction by loading can be quickly returned to the correct rotational direction. Therefore, the load traces quickly decrease and the display quality improves. Further, since a protective plate to prevent loading on the display face is not necessary, the production cost of the liquid crystal display device can be reduced.

Abstract: PURPOSE:To reduce the heating energy of a thermal head, by providing a fan for dissipating the heat accumulated in a thermal head and that accumulated in a heat sink and a guide means for guiding the air stream after heat dissipation to an ink film before thermal transfer to preheat said film. CONSTITUTION:Heat is accumulated in a thermal head 2 as a heat generating element generates heat at the time of thermal transfer and heat is also accumulated in a heat sink. These heats are dissipated by the air stream A due to the rotational driving of a cooling fan 10.

Since the heats accumulated in both of the thermal head 2 and the heat sink are put to practical use by this constitution, the energy of the thermal head 2 applied to the heat generating element is reduced by the quantity utilized in the preheating of the ink film 3.

Abstract: PURPOSE:To make the display coincident with a current status by making a signal level, display zero when a 1st intermediate frequency signal from an outdoor converter is lost during signal level display. CONSTITUTION:A BPF 16 extracts a higher frequency noise from a band of a demodulation signal from an FM demodulator 15 and a level detection circuit 17 detects the level of th extracted high frequency noise. On the other hand, a broadcast signal detection circuit 30 detects the presence of a broadcast signal from a demodulation signal from the FM demodulator 15. When the broadcast signal detection circuit 30 discriminates the absence of brought, a signal changeover circuit 40 switches an output from the above level detection circuit 17 to a prescribed level forcibly and the result is fed to an A/D converter 18. Thus, an arithmetic means 20 fetching the A/D converter 18 makes zero display to a display circuit 19. Thus, when no broadcast is in existence, since zero display is attained for the display circuit 19, the display is made coincident with a current status.
