A liquid crystal display element is provided which can clearly and simultaneously produce analog and digital displays. The analog display is produced by a first liquid crystal layer provided near a reflecting plate while the digital is made by a second liquid crystal layer disposed adjacent to the first liquid crystal layer.

DETAILED DESCRIPTION What we claim is: 1.
A reflection type liquid crystal display element comprising a first liquid crystal layer including first means for producing a digital display, and a second liquid crystal layer provided between said first liquid crystal layer and a reflecting plate and including second means for producing an analog display, said first and second means being segregated with respect to one another so that said analog and digital displays are not overlapping one another in the viewing direction from said first liquid crystal layer toward said reflecting plate.
2.
A reflection type liquid crystal display element as claimed in claim 1, wherein said element has a three substrate plate configuration in which said first liquid crystal layer is sandwiched between first and second substrate plates and said second liquid crystal layer is sandwiched between said second substrate plate and a third substrate plate.
3.
A reflection type liquid crystal display element as claimed in claim 1, wherein said first liquid crystal layer has a digital display section located in the central portion of said element and said second liquid crystal layer has an analog display section surrounding said digital display section.
4.
A reflection type liquid crystal display element as claimed in claim 1, wherein said element is used in a digital-analog time measuring instrument and said second liquid crystal layer has a first set of segments for indicating minutes and seconds and a second set of segments for indicating hours and minutes.




Description:
This invention relates to a liquid crystal display element which can provide both analog and digital displays with high clarity, and more particularly to a liquid crystal display element of the reflection type for use in a time measuring instrument.
The term "analog" used herein does not bear the same strict meaning of "analog" used in the field of electronics, but should be understood to mean a simulated analog of a dial plate of a clock
