Embodiment Construction

[0134] Some exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0135] FIG. 4 is a cross-sectional view of a transflective LCD according to one embodiment of the present invention.

[0136] Referring to FIG. 4, a transflective LCD according to one embodiment of the present invention includes a first substrate 110, a second substrate 130 whose inner surface is disposed facing the first substrate 110, and a substrate formed between the first substrate 110 and the second substrate 130. The liquid crystal layer 150 in between.

[0137] Preferably, the first and second substrates 110 and 130 are made of a glass substrate.

[0138] A first transparent electrode 115 made of a conductive oxide film such as indium tin oxide (ITO) is formed on the inner surface of the first substrate 110 . Preferably, the first transparent electrodes 115 extend in the first direction and serve as signal electrodes, and are distr...

Abstract

Disclosed is a transmissive and reflective type LCD. In the LCD, a second substrate faces a first substrate. Liquid crystal layer is formed between the first and second substrate. A first polarizing plate is formed on outer surface of the first substrate. A second polarizing plate is formed on outer surface of the second substrate. A backlight is arranged at a rear side of the first polarizing plate. A transparent transflective film is arranged between the first polarizing plate and the backlight and has a plurality of layers where a first and a second layer each having different refractivity indexes are alternatively stacked. The transparent transflective film partially reflects and transmits incident light. By a restoring process occurring between the transflective film and the backlight, a predetermined amount of the incident light is transmitted through the transflective film repeatedly, so that transmissivity and light efficiency are enhanced.

Description

technical field [0001] The present invention relates to a liquid crystal display, and more particularly, to a transflective liquid crystal display in which a display operation is performed in a reflective mode with low power consumption in a bright place with sufficient light quantity, and a display operation is performed in a high-brightness transmissive mode in a dark place with insufficient light quantity operate. Background technique [0002] In today's information-oriented world, electronic displays are playing a more important role. Various types of electronic displays are widely used in various industrial fields. [0003] Generally, an electronic display is a device that provides various visual information to people. In other words, electrical information signals output from various electronic devices are converted into visually recognizable optical information signals in electronic displays. Therefore, the electronic display acts as a bridge connecting people and ...
