Reflective liquid crystal display device

Abstract

Provided is a reflection type liquid crystal display capable of enhancing transmissivity of light transmitted from a liquid crystal element. The reflection type liquid crystal display 1 is provided with the liquid crystal element 100 having glass substrates 103 and 104 and a liquid crystal layer 107, a solar battery 101 provided with a glass substrate 400, a photovoltaic force generating part 405, and a light absorbing layer 404, a rubber sheet layer 102 intervening between the glass substrate 104 of the liquid crystal element 100 and the glass substrate 400 of the solar battery 101, and a non-figured driving circuit.

Description

technical field [0001] The present invention relates to a reflective liquid crystal display device, and more particularly to a reflective liquid crystal display device in which a solar cell is laminated inside a liquid crystal element. Background technique [0002] Conventionally, reflective liquid crystal display devices utilizing external light have been used as liquid crystal display devices characterized by low power consumption for the purpose of realizing thinner and lighter portable electronic devices and long-term battery operation. A semi-transmissive liquid crystal display device is also disclosed in this reflective liquid crystal display device. The reflector uses a semi-transmissive plate, which can be used as a reflective type in a bright place, and can be used as a transmissive type using a backlight in a dark place (for example, Japanese Patent Laying-Open No. 11 -002709 bulletin). [0003] Furthermore, in recent years, for example, a liquid crystal display d...

AI Technical Summary

Problems solved by technology

In general, a liquid crystal device is formed of a glass substrate with a refractive index of about 1.5. On the other hand, the refractive index of the air layer is as small as about 1.0, so there is a problem that the transmittance of light transmitted from the liquid crystal element is poor.
