Abstract

A liquid crystal display with improved display characteristics is disclosed. An OLED element is used as backlighting device resulting in a very flat liquid crystal display with a backlighting device. At least the front OLED drive electrode is formed such that it is at least partly light-transmissive, so that light from the OLED can be incident on the LCD element. The combination of an LCD element having internal reflectors or internal scattering elements and an OLED backlighting yields a thin overall display element which can be illuminated by sunlight during daytime and which can be illuminated using the OLED backlighting. Both the LCD element and the OLED element or OLED backlighting may represent information. For example, the actual information can be displayed on the LCD element, while the OLED element, primarily functioning as a backlighting device, can additionally represent a logo.
