Description

Transflective fringe field switching mode liquid crystal display device

The present invention relates to a transflective fringe field switched mode liquid crystal display device, and more particularly, to a transflective fringe field switched mode liquid crystal display device, which enables a single cell gap structure, obtains high quality and secures a wide viewing angle. And a transflective fringe field switching mode liquid crystal display device.

The liquid crystal display may be classified into a transmissive liquid crystal display device using a backlight as a light source and a reflective liquid crystal display device using natural light as a light source. Since the transmissive liquid crystal display uses a backlight as a light source, a bright image can be realized even in a dark environment, but there is a disadvantage in that power consumption is high by using the backlight. On the other hand, the reflection type liquid crystal display device consumes less power because it uses natural ambient light without using a backlight, but has a disadvantage in that it cannot be used when the surrounding environment is dark.

The semi-transmissive liquid crystal display device has been proposed to compensate for the disadvantages of the above-described transmissive liquid crystal display device and the reflective liquid crystal display device. The transflective liquid crystal display device can be used as a reflection type and a transmissive type as needed, so it has a relatively low power consumption and can be used in a dark environment.

The upper polarizing plate 400 and the lower polarizing plate 500 are disposed outside the upper substrate 200. The common electrode 110 and the pixel electrode 120 are formed on the lower substrate 100, and the color filter 210 is formed on the upper substrate 200 corresponding to the pixel electrode 120. Each pixel electrode 120 is divided into a transmission region through which a light source of a backlight (not shown) is transmitted and a reflection region capable of reflecting natural light. In this case, a reflector 140 capable of reflecting light is formed in the reflective region of the lower substrate 100. The pixel electrode 120 is formed of a comb teeth comb electrode 120a, and a slit 120b is formed between the comb teeth 120a.

The liquid crystal layer 3 advantageously serves as a lambda / 2 phase difference plate to switch from 0 to lambda / 2 when power is applied.

FIG. 5 is a diagram schematically illustrating a transmission state of light when power is not applied to the liquid crystal display in FIG. 3, and FIG. 6 is a diagram schematically illustrating a transmission state of light when power is applied to the liquid crystal display in FIG. 3. to be.

Referring to FIG. 5, when power is not applied to the liquid crystal display in the transmissive region, the light of the backlight (not shown) passes through the lower polarizing plate 5 to become 0 degree linear light and passes through the liquid crystal layer 3 as it is. And it is absorbed by the upper polarizing plate 4 having a polarization axis perpendicular to the lower polarizing plate 5 to form a dark state. In addition, in the reflective region, when power is not applied to the liquid crystal display, natural light passes through the upper polarizing plate 4 to be linearly polarized by 90 degrees and passes through the liquid crystal layer 3 as it is. Then, the circular polarized light passes through the phase difference unit 15, is reflected through the reflector 14, and becomes 0 degree linearly polarized light while passing through the phase difference unit 15 again. Subsequently, the 0 degree linearly polarized light passes through the liquid crystal layer 3 as it is and is absorbed by the upper polarizing plate 4, thereby achieving a dark state. When no power is applied to the liquid crystal display, normal black is formed.

Referring to FIG. 6, when power is applied to the liquid crystal display in the transmissive region, light of a backlight (not shown) passes through the lower polarizing plate 5 to become 0 degree linearly polarized light. At this time, since the liquid crystal layer 3 is driven to serve as a λ / 2 phase difference plate in which the liquid crystal is twisted by 45 degrees, the 0 degree linearly polarized light passes through the liquid crystal layer 3 and becomes 90 degrees linearly polarized light. As it passes through as it is, a white state is achieved. In addition, when power is applied to the liquid crystal display in the reflective region, natural light passes through the upper polarizing plate 4 and becomes linearly polarized by 90 degrees. At this time, since the liquid crystal layer 3 is driven to serve as a λ / 2 phase difference plate in which the liquid crystal is twisted 22.5 degrees, the 90 degree linearly polarized light passes through the liquid crystal layer 3 to be 135 degrees linearly polarized. Since the optical axis of the phase difference unit 15 is 90 degrees different from the incident linear polarization (135 degree linear polarization), the axis does not change even when the polarized light passes through the phase difference unit 15 again through the reflecting unit 14. The 135 degree linearly polarized light reflected and passed through the phase difference part 15 becomes 90 degree linearly polarized light while passing through the liquid crystal layer 3, and passes through the upper polarizing plate 4 as it is, thereby achieving a white state. When power is applied to the liquid crystal display, normal white is formed.

Although not shown in the transmission region in the above description, two phase difference portions (λ / 4 phase difference plates) orthogonal to each other may be formed, and two phase difference portions (λ /) in which light passing through the polarizing plate in the transmission region are orthogonal to each other (λ / Since the polarization direction does not change while passing through the 4-phase difference plate, it does not affect the optical path described above.

As illustrated in FIGS. 7 to 9, a first cross electrode C2 and a second cross electrode C3 may be further formed in the reflective region of the pixel electrode 12.

At least one first crossing electrode C2 is formed in parallel with the second pixel electrode S2 to be spaced apart from the second pixel electrode S2. At least one second crossing electrode C3 is formed in parallel with the third pixel electrode S3 to be spaced apart from the third pixel electrode S3.

For example, as illustrated in FIG. 7, the pixel electrode 12 in the reflective region has a first cross electrode C2 and a second cross electrode C3 intersecting the second pixel electrode S2 and the third pixel electrode S3. ) Can be crossed. Such a shape may be formed in a shape in which the pixel electrodes 12 of the reflective region illustrated in FIG. 4 are arranged in a square shape. In addition, as shown in FIG. 8, the electrodes vertical and horizontal to the rubbing axis may be removed from the pixel electrode 12 of the reflective region illustrated in FIG. 7.

As another example, as illustrated in FIG. 9, the pixel electrode 12 in the reflective region has a first crossing electrode C2 at an intersection hole H2 formed by the crossed second pixel electrode S2 and the third pixel electrode S3. ) And only the second cross electrode C3 may be formed to cross each other. In this case, the first cross electrode C2 and the second cross electrode C3 do not cross the second pixel electrode S2 or the third pixel electrode S3, respectively.

Through the structure of the pixel electrode 12 as shown in FIGS. 7 to 9, the average twist angle of the liquid crystal converges to 22.5 degrees in the reflection region when the power is applied, and the average twist angle of the liquid crystal is 45 degrees in the transmissive region. Converge. In addition, since the above-described structure of the pixel electrode 12 increases the driving voltage of the liquid crystal, the V-T curve in the transmission region and the V-R curve in the reflection region can be matched in the single cell gap structure.
