Display device and driving method thereof
First Claim
1. A display device comprising a first substrate on which a plurality of light emitting devices including a reflecting electrode is disposed;
- a second substrate made of a transparent material provided with a color filter and a transparent electrode;
a liquid crystal layer placed between said first substrate and said second substrate disposed in such a manner that a face of said light emitting devices and a face of said transparent electrode confront each other; and
a driving circuit for controlling a voltage to be applied to said liquid crystal layer, and selecting either a reflection display mode of displaying an image by reflecting ambient light with said reflecting electrode of said light emitting device or a self-emission display mode of displaying an image by light emission of said light emitting device.

Abstract
The invention provides a thin type display device provided with a simplified constitution and driving circuit, which offers an excellent visibility both in a light place and in a dark place.
Liquid crystal 70 is placed between a substrate 10 on which a plurality of light emitting devices 20 including a reflecting electrode 21 is disposed and a transparent substrate 60 provided with a transparent electrode 63 and a color filter 61. A driving circuit switches to either a reflection display mode of displaying an image by reflection of ambient light from the reflecting electrode 21 of the light emitting device 20, or a self-emission display mode of displaying an image by self light emission from the light emitting device 20.
