Title: Reflection type liquid crystal display device
Inventor: FUKUYOSHI KENZO
IPC: G02F1/1343
Filed: 1993-09-28
Abstract: PURPOSE:To provide the reflection type liquid crystal display device capable of making image display with a wide visual field angle without coloration regardless of the position of an external light source. CONSTITUTION:This reflection type liquid crystal display device is constituted by providing an observer's side electrode plate 2 arranged to face a rear surface electrode plate 1 with a light scattering layer 21 consisting essentially of a transparent resin and particulates dispersed into this transparent resin. The particulates having a small refractive index, optical average dispersion of <=0.09 and double rafraction of <=0.02 are applied by the transparent resin. Since the refractive index of the particulates is smaller than the refractive index of the transparent resin, a light scattering effect is high and since the optical average dispersion and double refractions are small, the coloration does not arise. The bright screen display free from the coloration is, therefore, made possible regardless of the position of the external light source.

Abstract: PURPOSE: To prevent the flowing of melted solder to neighboring input electrodes, to perform the processing for avoiding the concentration of stress in the shearing direction applied on the input electrodes, and to prevent the short circuits and the wire breaking between the electrodes. CONSTITUTION: The long side of a slit hole 26 in correspondence with each input electrode 28 has the irregular shape. The input electrode 28 is overlapped on a substrate electrode 30. A solder 32 is melted by heating, and both electrodes 28 and 30 are fixed. The melted solder 32 flows between a base 22 and a substrate 18A by capillary phenomenon. The flow of the solder to the neighboring input electrode 28 is blocked by forming a protruding part 26A on the long side of the slit hole 26 so as to form the irregularity and setting the base 22 connecting the neighboring input electrodes 28 in the nonlinear state. Furthermore, when a liquid cell and the substrates 18A and 18B are relatively moved, the respective independent deformations can be formed at the bonding part of the protruding part 26A and the individual input electrode 28.  The concentration of the stress in the shearing direction is avoided, and the strength is increased.
