Display apparatus, method for manufacturing and driving the same

Abstract

A display device of the invention comprises a reflection region and a light emitting region arranged in a display region. The reflection region includes a non-light emitting display element for reflecting external light and performing a display operation by a liquid crystal display element. The light emitting region includes a light emitting display element for directly modulating and performing a display operation by an organic electroluminescence element. The display device further includes a first substrate and a second substrate opposed with each other. A light modulating element and a light emitting element are arranged between the first substrate and the second substrate. A display device, and a method for manufacturing the same are provided to reduce the size of the device and costs, and achieve improved visibility in both outdoor and indoor areas.

Description

[0001] This application is a divisional application of the invention patent application with the application number "02132038.1" and the invention title "display device and its manufacturing and driving method" submitted by the applicant on September 6, 2002. technical field [0002] The present invention relates to a display device using a non-light-emitting display device such as a liquid crystal display device, a light-emitting display device such as an organic electroluminescent (EL) element, and the like, a manufacturing method, and a driving method thereof. In particular, it relates to a display device with a non-luminous display area and a light-emitting display area in a display area, a light-emitting display device, a manufacturing method thereof, and a driving circuit thereof. Background technique [0003] In recent years, mobile phones and mobile information terminals (PDA: Personal Date Assistant, personal data assistant), etc. have been widely used. Accordingly,...

Problems solved by technology

[0025] In addition, in the above-mentioned Japanese Patent Laid-Open No. 2001-43980, since there is a metal cathode on the side where the light is emitted, even though it is extremely thin, there will be a transmission loss caused by it.

In addition, because the cathode is extremely thin, there are problems in that it combines with the oxygen contained in the transparent conductive layer and the organic conductive layer formed thereon to cause performance degradation, and the influence of the temperature when forming the transparent conductive layer on the light emitting layer.

[0026] Also, according to the above-mentioned Japanese Patent Application Laid-Open No. 2000-173770, since the anode side is a transparent conductive film, which has higher impedance than the usual conductors, when the display screen is made, the power consumption caused by the transparent conductive film will cause the generation of an image.
