DETAILED DESCRIPTION
Hereinafter, embodiments will be explained in detail with reference to the accompanying drawings.

The display panel 110 receives a data signal DS based on an image data DATA to display an image. For example, the image data DATA may be two-dimensional plane image data. Alternatively, the image data DATA may include a left-eye image data and a right-eye image data for displaying a three-dimensional stereoscopic image.
The display panel 110 includes gate lines GL, data lines DL and a plurality of unit pixels UP. The gate line GL extends in a first direction D1 and the data line DL extends in a second direction D2 substantially perpendicular to the first direction D1. Each of the unit pixels UP includes a first sub pixel SP1, a second sub pixel SP2 and a third sub pixel SP3. The first sub pixel SP1 includes a thin film transistor 111 electrically connected to the gate line GL and the data line DL, a liquid crystal capacitor 113 and a storage capacitor 115 connected to the thin film transistor 111. Each of a structure of the second sub pixel SP2 and a structure of the third sub pixel SP3 is substantially the same as a structure of the first sub pixel SP1.
The gate driving part 120 generates a gate signal GS in response to a gate start signal STV and a gate clock signal CPV1 provided from the timing controlling part 140, and outputs the gate signal GS to the gate line GL. Specifically, the gate driving part 120 increases the gate signal GS from a gate off voltage to a gate on voltage in response to an activation of the gate start signal STV and the gate clock signal CPV1. In addition, the gate driving part 120 decreases the gate signal GS to the gate off voltage in response to a deactivation of the gate clock signal CPV1. For example, the gate off voltage may be about −7.5 volts (V) to about −6.5 volts (V), and the gate on voltage may be about 28 volts (V) to about 31 volts (V).
The data driving part 130 outputs the data signal DS based on the image data DATA to the data line DL, in response to a data start signal STH and a data clock signal CPV2 provided from the timing controlling part 140.
The timing controlling part 140 receives the image data DATA and a control signal CON from an outside. The control signal CON may include a horizontal synchronous signal Hsync, a vertical synchronous signal Vsyne and a clock signal CLK. The timing controlling part 140 generates the data start signal STH using the horizontal synchronous signal Hsync and outputs the data start signal STH to the data driving part 130. In addition, the timing controlling part 140 generates the gate start signal STV using the vertical synchronous signal Vsync and outputs the gate start signal STV to the gate driving part 120. In addition, the timing controlling part 140 generates the gate clock signal CPV1 and the data clock signal CPV2 using the clock signal CLK, outputs the gate clock signal CLK1 to the gate driving part 120 and outputs the data clock signal CPV2 to the data driving part 130. The timing controlling part 140 may further output a light source control signal LSC controlling a driving of the light source part 160.
The light source driving part 150 outputs a light source driving signal LSD driving the light source part 160 to the light source part 160 in response to the light source control signal LSC received from the timing controlling part 140.
The light source part 160 generates a light L in response to the light source driving signal LSD received from the light source driving part 150 to provide the light L to the display panel 110. The light source part 160 outputs the light L to the display panel 110 in a method of field sequential color driving method. For example, the light source part 160 may sequentially provide a red light, a green light and a blue light to the display panel 110. Alternatively, the light source part 160 may sequentially provide a yellow light and the blue light to the display panel 110. The light source part 160 may include a light emitting diode (LED) generating the light L.
FIG. 2 is a cross sectional view illustrating the unit pixel UP in the display panel 110 of FIG. 1.
Referring to FIGS. 1 and 2, the display panel 110 includes a first display substrate 200, a second display substrate 300 and a liquid crystal layer 400.
The first display substrate 200 includes a first base substrate 210, a thin film transistor 230, an organic insulating layer 250 and a pixel electrode 260.
The first base substrate 210 includes a first sub pixel area SPA1 in which the first sub pixel SP1 is formed, a second sub pixel area SPA2 in which the second sub pixel SP2 is formed, and a third sub pixel area SPA3 in which the third sub pixel SP3 is formed. The first sub pixel area SPA1 and the second sub pixel area SPA2 may be an area displaying a left-eye image of the three-dimensional stereoscopic image and the third sub pixel area SPA3 may be an area displaying a right-eye image of the three-dimensional stereoscopic image.
The thin film transistor 230 is formed on a front surface of the first base substrate 210, and includes a gate electrode 231 protruded from the gate line GL, a gate insulating layer 232 covering the gate electrode 231, a source electrode 233 protruded from the data line DL, and a drain electrode 234 spaced apart from the source electrode 233. The organic insulating layer 250 covers the thin film transistor 230. The pixel electrode 260 is formed on the organic insulating layer 250 and is electrically connected to the drain electrode 234 of the thin film transistor 230 through a contact hole formed through the organic insulating layer 250. The first display substrate 200 may further include a first polarizing plate 270 formed a rear surface of the first base substrate 210 and selecting a linearly polarized light.
The second display substrate 300 includes a second base substrate 310 facing the first base substrate 210, a color filter layer 320 formed on a front surface of the second base substrate 310, a common electrode 330 formed on the color filter layer 320, and a retarder layer 350 formed on a rear surface of the second base substrate 310.
The color filter layer 320 includes a first color filter 321 formed in the first sub pixel area SPA1, a second color filter 322 formed in the second sub pixel area SPA2, and a third color filter 323 formed in the third sub pixel area SPA3. The first color filter 321 and the second color filter 322 include at least one of a magenta color filter, a cyan color filter and a yellow color filter, and the third color filter 323 includes a white color filter. For example, the first color filter 321 may be the magenta color filter, the second color filter 322 may be the cyan color filter and the third color filter 323 may be the white color filter.
The retarder layer 350 includes a first retarder portion 351 formed in the first sub pixel area SPA1, a second retarder portion 352 formed in the second sub pixel area SPA2 and a third retarder portion 353 formed in the third sub pixel area SPA3. The first retarder portion 351 and the second retarder portion 352 transmit a first polarized light. Therefore, the first retarder portion 351 converts light transmitting the first color filter 321 into the first polarized light in the first sub pixel area SPA1 and the second retarder portion 352 converts light transmitting the second color filer 322 into the first polarized light in the second sub pixel area SPA2. Thus, the first retarder portion 351 first polarizes the light transmitting the first color filter 321 in the first sub pixel area SPA1 and the second retarder portion 352 first polarizes the light transmitting the second color filer 322 in the second sub pixel area SPA2. The third retarder portion 353 transmits a second polarized light different from the first polarized light. Therefore, the third retarder portion 353 converts light transmitting the third color filter 323 into the second polarized light in the third sub pixel area SPA3. Thus, the third retarder portion 353 second polarizes the light transmitting the third color filter 323 in the third sub pixel area SPA3. The first polarized light and the second polarized light may cross each other. The retarder layer 350 may include a film patterned retarder.
The second display substrate 300 may include a second polarizing plate 340 formed between the second base substrate 310 and the retarder layer 350 and selecting the linearly polarized light.

The liquid crystal layer 400 includes a liquid crystal of which an alignment is changed by an electric field between the pixel electrode 260 of the first display substrate 200 and the common electrode 330 of the second display substrate 300.
Referring to FIG. 1 again, the display apparatus 100 may further include a polarizing glass 170.
The polarizing glass 170 includes a left-eye glass portion 171 and a right-eye glass portion 172. The left-eye glass portion 171 has a light absorbing axis substantially the same as an axis of the first retarder portion 351 and an axis of the second retarder portion 352. Thus, the left-eye glass portion 171 transmits the first polarized light. The right-eye glass portion 172 has a light absorbing axis substantially the same as an axis of the third retarder portion 353. Thus, the right-eye glass portion 172 transmits the second polarized light.
FIGS. 3A to 3F are sequential diagrams illustrating a method of displaying the three-dimensional stereoscopic image using the display panel 110 of FIGS. 1 and 2.
Referring to FIGS. 3A and 3B, a red light RL is provided to the display panel 110. Specifically, the light source part 160 outputs the red line RL to the display panel 110 during a first field period of a frame period. The red light RL transmits through the first color filter 321 including the magenta color filter in the first sub pixel area SPA1 and is converted into the first polarized light by the first retarder portion 351. Thus, a red left-eye image RL1 is displayed in the first sub pixel area SPA1. In addition, the red light RL transmits through the third color filter 323 including the white color filter and is converted into the second polarized light by the third retarder portion 353. Thus, a red right-eye image RR1 is displayed in the third sub pixel area SPA3. In the figures generally, various lights are absorbed by particular color filters and thus do not pass through the particular color filters. For example, in FIG. 3A, the red light RL is absorbed by the second color filter 322 including the cyan color filter in the second sub pixel area SPA2 and thus does not pass through the second color filter 322.
Referring to FIGS. 3C and 3D, a green light GL is provided to the display panel 110. Specifically, the light source part 160 outputs the green light GL to the display panel 110 during a second field period next to the first field period of the frame period. The green light GL transmits through the second color filter 322 including the cyan color filter in the second sub pixel area SPA2 and is converted into the first polarized light by the second retarder portion 352. Thus, a green left-eye image GL is displayed in the second sub pixel area SPA2. In addition, the green light GL transmits through the third color filter 323 including the white color filter and is converted into the second polarized light by the third retarder portion 353. Thus, a green right-eye image GRI is displayed in the third sub pixel area SPA3.

Specifically, the light source part 160 outputs the blue light BL to the display panel 110 during a third field period next to the second field period of the frame period. The blue light BL transmits through the first color filter 321 including the magenta color filter in the first sub pixel area SPA1 and is converted into the first polarized light by the first retarder portion 351.

In addition, the blue light BL transmits through the second color filter 322 including the cyan color filter in the second sub pixel area SPA2 and is converted into the first polarized light by the second retarder portion 352. Thus, the blue left-eye image BL1 is displayed in the second sub pixel area SPA2. In addition, the blue light BL transmits through the third color filter 323 including the white color filter and is converted into the second polarized light by the third retarder portion 353. Thus, a blue right-eye image BR1 is displayed in the third sub pixel area SPA3. Thus, the three-dimensional stereoscopic image is displayed.

Referring to FIGS. 4A and 4B, a yellow light YL is provided to the display panel 110. Specifically, the light source part 160 outputs the yellow light YL to the display panel 110 during a first field period of a frame period. The yellow light YL transmits through the first color filter 321 including the magenta color filter in the first sub pixel area SPA1 and is converted into the first polarized light by the first retarder portion 351. Thus, a red image RI is displayed in the first sub pixel area SPA1. In addition, the yellow light YL transmits through the second color filter 322 including the cyan color filter in the second sub pixel area SPA2 and is converted into the first polarized light by the second retarder portion 352.

Referring to FIGS. 4C and 4D, a blue light BL is provided to the display panel 110. Specifically, the light source part 160 outputs the blue light BL to the display panel 110 during a second field period next to the first field period of the frame period. The blue light BL transmits through the first color filter 321 including the magenta color filter in the first sub pixel area SPA1 and is converted into the first polarized light by the first retarder portion 351. Thus, a blue image B1 is displayed in the first sub pixel area SPA1. In addition, the blue light BL transmits through the second color filter 322 including the cyan color filter in the second sub pixel area SPA2 and is converted into the first polarized light by the second retarder portion 352. Thus, a blue image BI is displayed in the second sub pixel area SPA2. In addition, the blue light BL transmits through the third color filter 323 including the white color filter in the third sub pixel area SPA3 and is converted into the second polarized light by the third retarder portion 353.

According to the present exemplary embodiment, the three-dimensional stereoscopic image is displayed during the first, second and third field periods in the field sequential color driving method, therefore a high speed driving is not required to the display apparatus 100. Thus, a driving speed of the display apparatus 100 may be decreased.
In addition, the left-eye image and the right-eye image respectively having the first polarization and the second polarization different from each other is displayed in the unit pixel UP including the first, second and third sub pixels SP1, SP2 and SP3, therefore a deterioration of a resolution may be prevented. Thus, display quality of the display apparatus 100 may be improved.
