Title:
TRANSFLECTIVE LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP3713501
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a transflective liquid crystal display device having a single cell gap configuration that phase variation in a reflection region and in a transmission region is controlled by the use of applied electric field so as to optimally illuminate the reflection region and the transmission region of the semitransmissive liquid crystal display device.
SOLUTION: The transflective liquid crystal display device includes an active element array substrate 400, a counter substrate 300, a liquid crystal layer 500 and a reflection plate 404. Liquid crystal molecules in the transmission region T are driven with an electric potential between a transparent pixel electrode 402 and a common electrode 302 and liquid crystal molecules in the reflection region R are driven with an electric potential between the transparent pixel electrode 402 and an auxiliary electrode 304 on the active element array substrate 400 or on the counter substrate 300.
