Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims priority from Japanese Application No. 2017-091363, filed on May 1, 2017, the contents of which are incorporated by reference herein in its entirety. 
     BACKGROUND 
     Technical Field 
     The present disclosure relates to a display device. 
     Description of the Related Art 
     Recent years have seen growing demands for display devices for use in, for example, mobile devices, such as mobile phones and electronic paper. In such a display device, each pixel includes a plurality of sub-pixels, which emit light of different colors. The display device makes the pixel display various colors by switching on and off display of the sub-pixels. Such display devices have been improved year after year in display characteristics, such as resolution and luminance. 
     Typically, in such a display device, each pixel is constituted by sub-pixels of red, green, and blue, or by adding a white sub-pixel to the red, green, and blue sub-pixels. Brightness and colors are expressed by controlling each pixel. Meanwhile, Japanese Patent Application Laid-open Publication No. 2016-206243 discloses a technique of performing display drive by independently controlling the output of the sub-pixels. 
     In a display device that performs the display drive by independently controlling the output of the sub-pixels, a color array of the sub-pixels (hereinafter, also called a pixel array) differs row by row, in some cases. When the display drive is performed in such a display device, deterioration in display quality, or so-called crosstalk, may occur depending on the driving order of the pixels. For example, when a single-colored window image is displayed at a central part of an image display panel, regions on both sides of the single-colored window image are brightened (or darkened). 
     For the foregoing reasons, there is a need for a display device that prevents the deterioration in display quality caused by the crosstalk. 
     SUMMARY 
     According to an aspect of the present disclosure, a display device includes an image display panel, the image display panel including: a plurality of sub-pixel rows, in each of which a plurality of sub-pixels to display respective different colors are periodically arrayed in a first direction, are regularly arranged in a second direction different from the first direction; a plurality of signal lines in parallel to a plurality of sub-pixel columns in which the sub-pixels are successively arranged in the second direction; and a plurality of scan lines that sequentially select each of the sub-pixel rows. Each of m (where m is an integer of two or greater) selector signals selects n (where n is an integer of one or greater) pairs of the signal lines, each pair supplied with two signals each having a mutually reverse polarity, within a period during which each of the sub-pixel rows is selected by corresponding one of the scan lines, and a sum of potential changes of the n pairs of the signal lines selected by each of the selector signals is substantially zero when each of the sub-pixel rows is sequentially selected by the corresponding scan line.

     DETAILED DESCRIPTION 
     Modes (embodiments) for carrying out the present disclosure will be described below in detail with reference to the drawings. The disclosure is given by way of example only, and various changes made without departing from the spirit of the disclosure and easily conceivable by those skilled in the art naturally fall within the scope of the present disclosure. The drawings may possibly illustrate the width, the thickness, the shape, and other elements of each unit more schematically than the actual aspect to simplify the explanation. These elements, however, are given by way of example only and are not intended to limit interpretation of the present disclosure. In the specification and the drawings, components similar to those previously described with reference to a preceding drawing are denoted by like reference numerals, and overlapping explanation thereof will be appropriately omitted. 
       FIG. 1  is a block diagram illustrating an exemplary configuration of a display device according to an embodiment of the present disclosure.  FIG. 2  is a conceptual diagram of an image display panel and an image display panel drive circuit of the display device according to the embodiment. 
     As illustrated in  FIG. 1 , a display device  10  includes a signal processor  20 , an image display panel  30 , an image display panel drive circuit  40 , a planar light source device  50 , a planar light source device control circuit  60 . The signal processor  20  transmits signals to components of the display device  10  and controls their operations. The image display panel  30  displays an image based on output signals from the signal processor  20 . The image display panel drive circuit  40  controls drive of the image display panel  30 . The planar light source device  50  illuminates the image display panel  30  from its back side. The planar light source device control circuit  60  controls drive of the planar light source device  50 . 
     The signal processor  20  is an arithmetic processor that controls operations of the image display panel  30  and the planar light source device  50 . The signal processor  20  is coupled to the image display panel drive circuit  40  for driving the image display panel  30  and to the planar light source device control circuit  60  for driving the planar light source device  50 . The signal processor  20  processes an input signal supplied from the outside, and generates an output signal and a planar light source device control signal. In other words, the signal processor  20  receives the input signal (red-green-blue (RGB) data) from an image output unit  12  of a control device  11 , and generates the output signal by performing predetermined data conversion processing on the input signal to output the output signal to the image display panel  30 . The signal processor  20  outputs the generated output signal to the image display panel drive circuit  40 , and outputs the generated planar light source device control signal to the planar light source device control circuit  60 . 
     Pixels  48  are arranged in a two-dimensional matrix of P 0 ×Q 0  pixels (P 0  pixels in the row direction and Q 0  pixels in the column direction) on the image display panel  30 . In the example illustrated in  FIG. 2 , the row direction corresponds to the X-direction, and the column direction corresponds to the Y-direction. Hereinafter, the X-direction is also called the “first direction”, and the Y-direction is also called the “second direction”. 
     Each of the pixels  48  includes a plurality of sub-pixels  49  for displaying different colors. The pixel  48  may include, for example, a first sub-pixel for displaying a first primary color (e.g., red), a second sub-pixel for displaying a second primary color (e.g., green), and a third sub-pixel for displaying a third primary color (e.g., blue), or may include a fourth sub-pixel for displaying a fourth color (i.e., white) in addition to the first, second, and third sub-pixels. 
     The present embodiment assumes that display drive is independently performed for each of the sub-pixels. In the present embodiment, in video processing (to be described later) by the signal processor  20 , the sub-pixels  49  for displaying the different colors are processed as one pixel unit for the sake of convenience. Specifically, partition of one pixel unit varies according to the video processing by the signal processor  20 . Examples of processing for performing the display drive for each of the sub-pixels include sub-pixel rendering. 
     In the present embodiment, the sub-pixels  49  for displaying the different colors are periodically arranged in the X-direction (first direction) to form a sub-pixel row. The sub-pixel rows are regularly arranged in the Y-direction (second direction) to form a pixel array. The pixel array will be described later. 
     The display device  10  is more specifically a transmissive color liquid crystal display device. The image display panel  30  is a color liquid crystal display panel, in which a color filter is provided for each of the first, second, and third sub-pixels. When the fourth sub-pixel is included, the fourth sub-pixel may be provided with a transparent resin layer. 
     The image display panel drive circuit  40  is a control device according to the present embodiment, and includes a signal output circuit  41  and a scan circuit  42 . The image display panel drive circuit  40  uses the signal output circuit  41  to hold and sequentially output video signals to the image display panel  30 . The signal output circuit  41  is electrically coupled to the image display panel  30  through signal lines DTL. The image display panel drive circuit  40  uses the scan circuit  42  to select the sub-pixels on the image display panel  30 , and controls on and off of switching elements (e.g., thin film transistors (TFTs)) for controlling operations (optical transmittance) of the sub-pixels. The scan circuit  42  is electrically coupled to the image display panel  30  through scan lines SCL. 
     The scan lines SCL and the signal lines DTL are linear metal wiring, and three-dimensionally intersect with each other in directions substantially orthogonal to each other. 
     The planar light source device  50  is disposed on the back side of the image display panel  30 , and emits light toward the image display panel  30  to illuminate the image display panel  30 . The planar light source device  50  emits the light to the entire image display panel  30  to brighten the image display panel  30 . The planar light source device control circuit  60  controls, for example, the light quantity of the light emitted from the planar light source device  50 . Specifically, the planar light source device control circuit  60  controls the light quantity of the light (intensity of the light) irradiating the image display panel  30  by adjusting a voltage or a duty ratio of power supplied to the planar light source device  50  based on the planar light source device control signal output from the signal processor  20 . 
     The signal processor  20  processes the input signal to generate the output signal for determining display gradations of the sub-pixels  49 , and outputs the generated output signal to the image display panel drive circuit  40 . As described above, the present embodiment assumes that the display drive is independently performed for each of the sub-pixels, and thus is applicable to, for example, a configuration in which sub-pixel rendering is performed. 
       FIG. 3  is a schematic diagram illustrating an example of the pixel array and an internal configuration of the signal output circuit in a display device according to a comparative example. The comparative example illustrated in  FIG. 3  represents a configuration example including the first sub-pixels for displaying the first primary color (e.g., red), the second sub-pixels for displaying the second primary color (e.g., green), and the third sub-pixels for displaying the third primary color (e.g., blue). 
       FIG. 4  is a schematic diagram illustrating a state where a single-colored window image is displayed at a central part of the image display panel. In the example illustrated in  FIG. 4 , a single-colored window image  30 W is displayed at a central part of a display region  31  of the image display panel  30 . 
     In the comparative example illustrated in  FIG. 3 , the first sub-pixel (red), the second sub-pixel (green), and the third sub-pixel (blue) are sequentially arrayed in this order in each sub-pixel row in the display region  31  of the image display panel  30 . These sub-pixels are arranged in the Y direction such that each of the first sub-pixel (red), the second sub-pixel (green), and the third sub-pixel (blue) belonging to a first sub-pixel row is shifted in the X direction by one sub-pixel with respect to a corresponding sub-pixel belonging to a second sub-pixel row adjacent to the first sub-pixel row. 
     Also in the comparative example illustrated in  FIG. 3 , in the display region  31  of the image display panel  30 , each signal line DTL is coupled alternately in the Y direction to two consecutive sub-pixels  49  belonging to a first sub-pixel column and two consecutive sub-pixels  49  belonging to a second sub-pixel column adjacent to the first sub-pixel column. More specifically, an example is illustrated in which, in N−1th (where N is an integer of two or greater) and Nth sub-pixel rows, each signal line DTL is coupled to a part of the sub-pixels  49  belonging to a sub-pixel column on the right side in  FIG. 3  of the signal line DTL, and, in N+1th and N+2th sub-pixel rows, each signal line DTL is coupled to a part of the sub-pixels  49  belonging to a sub-pixel column on the left side in  FIG. 3  of the signal line DTL. 
     In the signal output circuit  41  according to the comparative example illustrated in  FIG. 3 , each of a first selector signal SEL 1 , a second selector signal SEL 2 , and a third selector signal SEL 3  selects a pair of the signal lines DTL each supplied with either of a first source signal S 1  and a second source signal S 2  each having a mutually reverse polarity. For example, assuming a common electrode COML to have a reference potential, the first source signal S 1  has a potential higher than the reference potential (hereinafter, referred to as a positive (+) polarity), and the second source signal S 2  has a potential lower than the reference potential (hereinafter, referred to as a negative (−) polarity). The magnitude of the potential +V of the first source signal S 1  relative to the potential of the common electrode COML is substantially equal to the magnitude of the potential −V of the second source signal S 2  relative to the potential of the common electrode COML. 
     Specifically, a signal line DTL 1  is supplied with the first source signal S 1  having the positive (+) polarity selected by the first selector signal SEL 1 . 
     A signal line DTL 2  is supplied with the second source signal S 2  having the negative (−) polarity selected by the first selector signal SEL 1 . 
     A signal line DTL 3  is supplied with the first source signal S 1  having the positive (+) polarity selected by the second selector signal SEL 2 . 
     A signal line DTL 4  is supplied with the second source signal S 2  having the negative (−) polarity selected by the second selector signal SEL 2 . 
     A signal line DTL 5  is supplied with the first source signal S 1  having the positive (+) polarity selected by the third selector signal SEL 3 . 
     A signal line DTL 6  is supplied with the second source signal S 2  having the negative (−) polarity selected by the third selector signal SEL 3 .

     The inventors of the present disclosure have found the following as illustrated in  FIG. 3 : When the selection of the scan line SCL shifts with the single-colored window image  30 W being displayed at the central part of the display region  31  of the image display panel  30 , regions  30 C on both sides in the X-direction (first direction) of the window image  30 W are brightened (or darkened) if the sum of the potential changes of the respective signal lines DTL selected by each of the selector signals is not substantially zero (≈0). 
     Coupling capacitance C acts between the common electrode COML and the signal lines DTL. As a result, when the selection of the scan line SCL shifts and the sum of the potential changes of the respective signal lines DTL selected by each of the selector signals is biased toward the positive (+) direction or the negative (−) direction, the potential of the common electrode COML is changed by the coupling capacitance C acting between the common electrode COML and the signal lines DTL. Consequently, in the case of the comparative example illustrated in  FIG. 3 , when the selection of the scan line SCL shifts and the sum of the potential changes of the respective signal lines DTL selected by each of the selector signals is not substantially zero (≈0), the potential change of the common electrode COML may cause crosstalk that deteriorates display quality in the X-direction (first direction). 
     As described above, in the display device  10  according to the embodiment illustrated in  FIG. 7 , the sum of the potential changes of the respective signal lines selected by each of the selector signals is substantially zero (≈0) when the selection of the scan line SCL shifts.

     First Modification 
       FIG. 23  is a schematic diagram illustrating a first modification of the pixel array and the internal configuration of the signal output circuit in the display device according to the embodiment. Similarly to the example illustrated in  FIG. 7 , the first modification illustrated in  FIG. 23  represents a configuration example including the first sub-pixel for displaying the first primary color (e.g., red), the second sub-pixel for displaying the second primary color (e.g., green), and the third sub-pixel for displaying the third primary color (e.g., blue). The frameworks of the signal output circuit  41 , the scan circuit  42 , and the image display panel  30  are not depicted in the example illustrated in  FIG. 23 . 
     In the first modification illustrated in  FIG. 23 , the first sub-pixel (red), the second sub-pixel (green), and the third sub-pixel (blue) are sequentially arrayed in this order in each sub-pixel row, and these sub-pixels are arranged in the Y direction such that each of the first sub-pixel (red), the second sub-pixel (green), and the third sub-pixel (blue) belonging to an even-numbered sub-pixel row is shifted in the X direction by one sub-pixel with respect to a corresponding sub-pixel belonging to an odd-numbered row. 
     In the first modification illustrated in  FIG. 23 , each signal line DTL is coupled alternately in the second direction to one sub-pixel  49  belonging to the first sub-pixel column and another sub-pixel  49  belonging to the second sub-pixel column adjacent to the first sub-pixel column. Specifically, an example is illustrated in which, in the N−1th (where N is an integer of two or greater) and N+1th sub-pixel rows, each signal line DTL is coupled to a part of the sub-pixels  49  belonging to a sub-pixel column on the right side in  FIG. 23  of the signal line DTL, and, in the Nth and N+2th sub-pixel rows, each signal line DTL is coupled to a part of the sub-pixels  49  belonging to a sub-pixel column on the left side in  FIG. 23  of the signal line DTL.

     Similarly to the example illustrated in  FIG. 7 , in the second modification illustrated in  FIG. 28 , each signal line DTL is coupled alternately in the Y direction to two consecutive sub-pixels  49  belonging to the first sub-pixel column and two consecutive sub-pixels  49  belonging to the second sub-pixel column adjacent to the first sub-pixel column. Specifically, an example is illustrated in which, in the N−1th (where N is an integer of two or greater) and Nth sub-pixel rows, each signal line DTL is coupled to a part of the sub-pixels  49  belonging to a sub-pixel column on the right side in  FIG. 28  of the signal line DTL, and, in the N+1th and N+2th sub-pixel rows, each signal line DTL is coupled to a part of the sub-pixels  49  belonging to a sub-pixel column on the left side in  FIG. 28  of the signal line DTL. 
     In the second modification illustrated in  FIG. 28 , each of the first selector signal SEL 1 , the second selector signal SEL 2 , and the third selector signal SEL 3  selects a pair of the signal lines DTL each supplied with either of the first source signal S 1  and the second source signal S 2  each having a mutually reverse polarity and a pair of the signal lines DTL each supplied with either of a third source signal S 3  and a fourth source signal S 4  each having a mutually reverse polarity. The magnitude of the potential +V of the first source signal S 1  relative to the potential of the common electrode COML is substantially equal to the magnitude of the potential −V of the second source signal S 2  relative to the potential of the common electrode COML. The magnitude of the potential +V of the third source signal S 3  relative to the potential of the common electrode COML is substantially equal to the magnitude of the potential −V of the fourth source signal S 4  relative to the potential of the common electrode COML. In this example, to display the single-colored window image  30 W illustrated in  FIG. 4 , the magnitude of the potential +V of the first source signal S 1  relative to the potential of the common electrode COML, the magnitude of the potential −V of the second source signal S 2  relative to the potential of the common electrode COML, the magnitude of the potential +V of the third source signal S 3  relative to the potential of the common electrode COML, and the magnitude of the potential −V of the fourth source signal S 4  relative to the potential of the common electrode COML are substantially equal to one another.

     Similarly to the first modification illustrated in  FIG. 23 , in the third modification illustrated in  FIG. 36 , the first sub-pixel (red), the second sub-pixel (green), and the third sub-pixel (blue) are sequentially arrayed in this order in each sub-pixel row, and these sub-pixels are arranged in the Y direction such that each of the first sub-pixel (red), the second sub-pixel (green), and the third sub-pixel (blue) belonging to the even-numbered sub-pixel row is shifted in the X direction by one sub-pixel with respect to a corresponding sub-pixel belonging to the odd-numbered row. 
     Similarly to the first modification illustrated in  FIG. 23 , in the third modification illustrated in  FIG. 36 , each signal line DTL is coupled alternately in the Y direction to one sub-pixel  49  belonging to the first sub-pixel column and another sub-pixel  49  belonging to the second sub-pixel column adjacent to the first sub-pixel column. Specifically, an example is illustrated in which, in the N−1th (where N is an integer of two or greater) and N+1th sub-pixel rows, each signal line DTL is coupled to a part of the sub-pixels  49  belonging to a sub-pixel column on the right side in  FIG. 36  of the signal line DTL, and, in the Nth and N+2th sub-pixel rows, each signal line DTL is coupled to a part of the sub-pixels  49  belonging to a sub-pixel column on the left side in  FIG. 36  of the signal line DTL.

The magnitude of the potential +V of the third source signal S 3  relative to the potential of the common electrode COML is substantially equal to the magnitude of the potential −V of the fourth source signal S 4  relative to the potential of the common electrode COML.

The magnitude of the potential −V of the first source signal S 1  relative to the potential of the common electrode COML is substantially equal to the magnitude of the potential +V of the second source signal S 2  relative to the potential of the common electrode COML. The magnitude of the potential −V of the third source signal S 3  relative to the potential of the common electrode COML is substantially equal to the magnitude of the potential +V of the fourth source signal S 4  relative to the potential of the common electrode COML.

     Seventh Modification 
       FIG. 60  is a schematic diagram illustrating a seventh modification of the pixel array and the internal configuration of the signal output circuit in the display device according to the embodiment. Similarly to the fourth modification illustrated in  FIG. 39 , the fifth modification illustrated in  FIG. 46 , and the sixth modification illustrated in  FIG. 53 , the seventh modification illustrated in  FIG. 60  represents a configuration example including the first sub-pixel for displaying the first primary color (e.g., red), the second sub-pixel for displaying the second primary color (e.g., green), the third sub-pixel for displaying the third primary color (e.g., blue), and the fourth sub-pixel for displaying the fourth color (specifically, white). The frameworks of the signal output circuit  41 , the scan circuit  42 , and the image display panel  30  are also not depicted in the example illustrated in  FIG. 60 . 
     Similarly to the sixth modification illustrated in  FIG. 53 , in the seventh modification illustrated in  FIG. 60 , the first sub-pixel (red), the second sub-pixel (green), the third sub-pixel (blue), and the fourth sub-pixel (white) are sequentially arrayed in this order in each sub-pixel row. These sub-pixels are arranged in the Y direction such that each of the first sub-pixel (red), the second sub-pixel (green), the third sub-pixel (blue), and the fourth sub-pixel (white) belonging to the even-numbered sub-pixel row is shifted in the X direction by two sub-pixels with respect to a corresponding sub-pixel belonging to the odd-numbered row. 
     Similarly to the example illustrated in  FIG. 7 , the second modification illustrated in  FIG. 28 , and the fifth modification illustrated in  FIG. 46 , the seventh modification illustrated in  FIG. 60  represents an example in which each signal line DTL is coupled alternately in the Y direction to two consecutive sub-pixels  49  belonging to a first sub-pixel column and two consecutive sub-pixels  49  belonging to a second sub-pixel column adjacent to the first sub-pixel column. Specifically, an example is illustrated in which, in the N−1th (where N is an integer of two or greater) and Nth sub-pixel rows, each signal line DTL is coupled to a part of the sub-pixels  49  belonging to a sub-pixel column on the left side in  FIG. 60  of the signal line DTL, and, in the N+1th and N+2th sub-pixel rows, each signal line DTL is coupled to a part of the sub-pixels  49  belonging to a sub-pixel column on the right side in  FIG. 60  of the signal line DTL. 
     In the seventh modification illustrated in  FIG. 60 , each of the first selector signal SEL 1 , the second selector signal SEL 2 , and the third selector signal SEL 3  selects a pair of the signal lines DTL each supplied with either of the first source signal S 1  and the second source signal S 2  each having a mutually reverse polarity, a pair of the signal lines DTL each supplied with either of the third source signal S 3  and the fourth source signal S 4  each having a mutually reverse polarity, a pair of the signal lines DTL each supplied with either of the fifth source signal S 5  and the sixth source signal S 6  each having a mutually reverse polarity, and a pair of the signal lines DTL each supplied with either of the seventh source signal S 7  and the eighth source signal S 8  each having a mutually reverse polarity. The magnitude of the potential +V of the first source signal S 1  relative to the potential of the common electrode COML is substantially equal to the magnitude of the potential −V of the second source signal S 2  relative to the potential of the common electrode COML. The magnitude of the potential +V of the third source signal S 3  relative to the potential of the common electrode COML is substantially equal to the magnitude of the potential −V of the fourth source signal S 4  relative to the potential of the common electrode COML. The magnitude of the potential +V of the fifth source signal S 5  relative to the potential of the common electrode COML is substantially equal to the magnitude of the potential −V of the sixth source signal S 6  relative to the potential of the common electrode COML. The magnitude of the potential +V of the seventh source signal S 7  relative to the potential of the common electrode COML is substantially equal to the magnitude of the potential −V of the eighth source signal S 8  relative to the potential of the common electrode COML. In this example, to display the single-colored window image  30 W illustrated in  FIG. 4 , the magnitude of the potential +V of the first source signal S 1  relative to the potential of the common electrode COML, the magnitude of the potential −V of the second source signal S 2  relative to the potential of the common electrode COML, the magnitude of the potential +V of the third source signal S 3  relative to the potential of the common electrode COML, the magnitude of the potential −V of the fourth source signal S 4  relative to the potential of the common electrode COML, the magnitude of the potential +V of the fifth source signal S 5  relative to the potential of the common electrode COML, the magnitude of the potential −V of the sixth source signal S 6  relative to the potential of the common electrode COML, the magnitude of the potential +V of the seventh source signal S 7  relative to the potential of the common electrode COML, and the magnitude of the potential −V of the eighth source signal S 8  relative to the potential of the common electrode COML are substantially equal to one another.

     In the seventh modification illustrated in  FIG. 60 , when each of the sub-pixel columns is sequentially selected, the sum of the potential changes of the signal lines DTL 1 , DTL 2 , DTL 7 , DTL 8 , DTL 13 , DTL 14 , DTL 19 , and DTL 20  selected by the first selector signal SEL 1  is substantially zero (≈0) as illustrated in  FIGS. 61 to 69 .

     The number of colors displayed by the sub-pixels, the number of pixel arrays, and the number of selector signals are not limited to those described above. The display device according to the embodiment only needs to be configured as follows: the sub-pixel rows, in which the sub-pixels  49  for displaying the different colors are periodically arranged in the X-direction (first direction), are regularly arranged in the Y-direction (second direction); each of m (where m is an integer of two or greater) selector signals selects n (where n is an integer of one or greater) pairs of the signal lines DTL each supplied with two signals each having a mutually reverse polarity within a period during which each of the sub-pixel rows is selected by corresponding one of the scan lines SCL; and the sum of the potential changes of the n pairs of the signal lines DTL selected by each of the selector signals is substantially zero (≈0) when each of the sub-pixel columns is sequentially selected by the scan line SCL. 
     The description above has illustrated the case where the single-colored window image  30 W is displayed at the central part of the display region  31  of the image display panel  30 . However, the effect of the present embodiment is not limited to this case. The present embodiment can also exhibit the effect when an ordinary moving image or still image is displayed, for example. That is, even when an ordinary moving image or still image is displayed, the sum of the potential changes of the respective signal lines selected by each of the selector signals is substantially zero (≈0), thereby preventing the deterioration in display quality caused by the crosstalk. 
     As described above, the display device  10  according to the present embodiment includes the image display panel  30  including: the sub-pixel rows, in which the sub-pixels  49  for displaying the different colors are periodically arranged in the X-direction (first direction), are regularly arranged in the Y-direction (second direction); the signal lines DTL provided parallel to the sub-pixel columns in which the sub-pixels  49  are successively arranged in the Y-direction (second direction); and the scan lines SCL that sequentially select each row of the sub-pixel columns. The display device  10  is configured such that each of the m (where m is an integer of two or greater) selector signals (first selector signal SEL 1 , second selector signal SEL 2 , and third selector signal SEL 3 ) selects the n (where n is an integer of one or greater) pairs of the signal lines DTL each supplied with two signals each having a mutually reverse polarity within the period during which each of the sub-pixel rows is selected by corresponding one of the scan lines SCL, and the sum of the potential changes of the n pairs of the signal lines DTL selected by each of the selector signals (first selector signal SEL 1 , second selector signal SEL 2 , and third selector signal SEL 3 ) is substantially zero when each of the sub-pixel columns is sequentially selected by the scan line SCL.

Each of the first selector signal SEL 1 , the second selector signal SEL 2 , and the third selector signal SEL 3  selects a pair of the signal lines each supplied with either of the first source signal S 1  and the second source signal S 2  each having a mutually reverse polarity, selects a pair of the signal lines each supplied with either of the third source signal S 3  and the fourth source signal S 4  each having a mutually reverse polarity, selects a pair of the signal lines each supplied with either of the fifth source signal S 5  and the sixth source signal S 6  each having a mutually reverse polarity, and selects a pair of the signal lines each supplied with either of the seventh source signal S 7  and the eighth source signal S 8  each having a mutually reverse polarity. 
     With any of the configurations described above, the sum of the potential changes of the respective signal lines selected by each of the selector signals is substantially zero (≈0) when each of the sub-pixel columns is sequentially selected, thereby preventing the deterioration in display quality caused by the crosstalk. 
     The components of the embodiment described above can be combined as appropriate. The present disclosure can naturally provide other advantageous effects that are provided by the aspects described in the embodiments above and are clearly defined by the description in the present specification or appropriately conceivable by those skilled in the art.
