Problems solved by technology

However, transmissive VA type LCD devices are not used due to their high energy consumption
[0019] In contrast, reflective VA-type LCD devices can reduce power consumption since no backlight is used, but they cannot be used when the external natural light is low

Embodiment Construction

[0034] Preferred embodiments will be described in detail with reference to examples illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0035] The VA type transflective LCD device includes a reflective part and a projective part in a unit pixel area, thereby providing the function of the transmissive LCD device as well as the function of the reflective LCD device. The VA type transflective LCD device can utilize light from a backlight unit as well as natural light or artificial light, and thus can have advantages of reduced power consumption and not being limited by external environments.

[0036] 1 is a partial plan view of a pixel portion in an array substrate of a VA-type multi-domain LCD device according to a first embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line I-I' in FIG. 1 .

[0037] As shown in FIGS. 1 and 2 , the V...

Abstract

The present invention discloses a transflective LCD device that can selectively use a reflective mode and a transmitission mode in a VA type transflective LCD device including multidomained. The transflective LCD device increases the aperture ratio by that the area of transmission part is bigger than the reflection part. Ensuring a total storage capacitance, improving an image quality character and a visual angle character by the storage capacitance formed between the multidomain formed in the VA type transflective LCD device.

Description

technical field [0001] The present invention relates to a liquid crystal display (LCD) device, in particular to a transflective LCD device which can selectively apply a reflective mode and a transmissive mode in a vertical alignment mode LCD device. Background technique [0002] Generally, Braun tubes, ie, cathode ray tubes (CRTs), are widely used in display devices to display image data on a screen, but the use of CRTs is limited due to the large size of Braun tubes compared with their display areas. Convenience. [0003] Now, with the development of the electronics industry, it has developed from a display device limited to a television (TV) Braun tube to a personal computer, a notebook computer, a wireless terminal, an automobile dashboard and a display panel. In addition, since the development of information communication makes it possible to transmit a large amount of image data, a next-generation display device capable of processing and realizing a large amount of ima...
