As shown in Figure 2,2m scan line 12 is divided into m the first scan line 12A and m the second scan line 12B.Each first scan line 12A and each second scan line 12B are along Y-direction alternate configurations (namely the second scan line 12B is positioned at the gap of each adjacent first scan line 12A).Connect at the first scan line 12A and belong at adjacent 2 the element row R of Y-direction and to be connected to (position that is directions X is different) n first display element E1 on different holding wire 14.In other words, on the first scan line 12A, jointly connect the first display element E1 of the even column in the element row R of the first display element E1 of the odd column in the element row R of odd-numbered line and even number line.In addition, connect at the second scan line 12B and belong at adjacent 2 the element row R of Y-direction and to be connected to n the second display element E2 on different holding wire 14.Namely the second display element E2 of the odd column in the element row R of the second display element E2 of the even column in the element row R of odd-numbered line and even number line is for the second scan line 12B, public connection.As mentioned above, only connect a plurality of the first display element E1 at the first scan line 12A, only connect a plurality of the second display element E2 at the second scan line 12B.

Fig. 4 is the timing diagram (timing chart) for the action of explanation display unit 100.The scan line drive circuit 32 of Fig. 2 as shown in Figure 4, with given order to the sweep signal Y of each scan line 12 outputs (YA[1]～YA[m], YB[1]～YB[m]) be set as significant level, between each selecting period during constituent parts in (vertical scanning period) F, (horizontal scan period) H selects each of 2m scan line 12 successively.Sweep signal YA[1]～YA[m] to each first scan line 12A output, sweep signal YB[1]～YB[m] each second scan line 12B is exported.If describe in further detail, scan line drive circuit 32 is selected each of 2m scan line 12 successively according to the order of arranging along Y-direction.The first scan line 12A and the second scan line 12B be along the Y-direction alternate configurations, so scan line drive circuit 32 is as shown in Figure 4, and H alternate selection the first scan line 12A and the second scan line 12B between each selecting period.

Control circuit 40 gated sweep line drive circuits 32 and the signal-line driving circuit 34 of Fig. 2.For example control circuit 40 is exported synchronizing signal, control signal to scan line drive circuit 32 and signal-line driving circuit 34, and gradation data D and data select signal SEL are exported signal-line driving circuit 34.The gray scale of each pixel in each of gradation data D appointment the first image GA and the second image GB.Data select signal SEL as shown in Figure 4, select H between the selecting period of the first scan line 12A (sweep signal (YA[1]～YA[m] in any one become H between the selecting period of significant level) be set to high level, and between the selecting period of selecting the second scan line 12B H (sweep signal YB[1]～YB[m] in any one become H between the selecting period of significant level) be set to low level.

The signal-line driving circuit 34 of Fig. 2 H between each selecting period exports the alive data voltage X[1 that executes that specifies each display element E side by side to n holding wire 14]～X[n].Select i capable (between the selecting period of the scan line 12 of i=1～2m) in H, to the j row (the data voltage X[j of holding wire 14 outputs of j=1～n)] be set as and the magnitude of voltage corresponding to the gray scale of the display element E appointment that belongs to the capable j row of i.

Schematically illustrate the data voltage X[j that the holding wire 14 of j row is supplied with in Fig. 4] and data voltage X[j+1 that the holding wire 14 of (j+1) row is supplied with].In addition, Fig. 5 means the schematic diagram in the content of the shown image of element portion Q.The demonstration of F during the part (A) of Fig. 5 illustrates f unit, the demonstration of F during the part (B) of Fig. 5 illustrates (f+1) individual unit.As shown in Figure 4, signal-line driving circuit 34 becomes in H between the selecting period of high level (selecting the first scan line 12A) at data select signal SEL, generate the data voltage X[1 corresponding with the gradation data D of the first image GA]～X[n], to each holding wire 14 outputs, become in H between low level selecting period (selecting the second scan line 12B) at data select signal SEL, generate the data voltage X[1 corresponding with the gradation data D of the second image GB]～X[n], to each holding wire 14 outputs.

Only connect a plurality of the first display element E1 on the first scan line 12A, so selecting between the selecting period of the first scan line 12A in H, what be connected to n the first display element E1 on this first scan line 12A applies voltage according to data voltage X[1]～X[n] (the gradation data D of the first image GA) be set.Equally, selecting between the selecting period of the second scan line 12B in H, what be connected to n the second display element E2 on this second scan line 12B applies voltage according to data voltage X[1]～X[n] (the gradation data D of the second image GB) be set.Therefore, as shown in Figure 5, show the first image GA at the first display element E1, and show the second image GB at the second display element E2.

As mentioned above, in this form, only connect the first display element E1 at the first scan line 12A, and only connect the second display element E2 at the second scan line 12B, so the data voltage X[1 of H to 14 outputs of each holding wire between selecting period]～X[n] generate according to the gradation data D of public image (GA, GB).Therefore, have advantages of not need to be between each selecting period processing or the structure of complexity of gradation data D of the gradation data D of synthetic the first image GA of H and the second image GB.

Except above action, signal-line driving circuit 34 is changed to the opposing party's mode according to the voltage that applies each display element E from a side of positive polarity and negative polarity in the given cycle, select the data voltage X[1 for given reference voltage (for example voltage of opposite electrode)]～X[n] polarity.If describe in further detail, signal-line driving circuit 34 is controlled data voltage X[1 according to the mode that alive polarity satisfies following condition of executing of each display element E]～X[n].In Fig. 4 remarks data voltage X[j] and data voltage X[j+1] separately polarity (+,-).Equally, the symbol "+" in Fig. 5 means that the voltage that applies of display element E is positive polarity, and symbol "-" means that the voltage that applies of display element E is negative polarity.

Signal-line driving circuit 34 at each adjacent holding wire 14 of directions X, is set as opposite polarity to the data voltage of the output of H between each selecting period (X[j], X[j+1]) as shown in Figure 4.Therefore, as shown in Figure 5, each first display element E1 of the odd-numbered line in individual the first display element E1 of the n on being connected to the first identical scan line 12A and each first display element E1 of even number line apply voltage and become opposite polarity.Equally, each second display element E2 of the odd-numbered line in individual the second display element E2 of the n on being connected to the second identical scan line 12B and each second display element E2 of even number line apply voltage and become opposite polarity.

In addition, signal-line driving circuit 34 as shown in Figure 4, H between 2 selecting periods before and after mutually (select H between the selecting period of the first scan line 12A and select H between the selecting period of the second scan line 12B) is as unit, the polarity reversal of data voltage X.For example, at sweep signal YA[1] and sweep signal YB[1] H between 2 selecting periods of high level become respectively, data voltage X[j] be set as positive polarity, at sweep signal YA[2] and sweep signal YB[2] become respectively H between 2 selecting periods of high level, data voltage X[j] put upside down and be negative polarity.Therefore, as shown in Figure 5, if be conceived to be connected to 2m display element E on same signal line 14, take at adjacent the first display element E1 of Y-direction and the second display element E2 as unit, execute alive polarity reversal.

Signal-line driving circuit 34 as shown in Figure 4, F is the polarity reversal of the data voltage X that display element E is supplied with during constituent parts.Therefore, during f unit shown in the part (A) of Fig. 5 during (f+1) the individual unit shown in the part (B) of F and Fig. 5 in F, each display element E executes alive polarity reversal.

Then, Fig. 6 means during f unit in F, at the image (partly (A)) of the first display direction output with at the schematic diagram of the image (partly (B)) of the second display direction output.The first display direction and the second display direction are different directions for display unit 100.For example the first image GA and the second image GB are that when mutually having the stereo-picture of parallax, the first display direction is equivalent to the direction of observer's left eye, and the second display direction is equivalent to the direction of observer's right eye.As shown in the part (A) of Fig. 6, from the display light of the first display element E1 in the first display direction outgoing, the first image GA exports at the first display direction, as shown in the part (B) of Fig. 6, in the second display direction outgoing, the second image GB exports at the second display direction from the display light of the second display element E2.F during (f+1) individual unit, too.

When specifying identical gray scale by gradation data D, according to executing alive polarity, the gray scale of actual display element E is different sometimes.Therefore, F during unit, if the voltage that applies of whole the first display element E1 (perhaps whole the second display element E2) is identical polar, even across F during a plurality of units, when specifying identical gray scale, also has F during constituent parts, the problem of the gray scale change of the first display element E1 (and then flicker obviously).In this form, applying voltage and be the first display element E1 of positive polarity and applying voltage is that the first display element E1 of negative polarity mixes in F during a unit and exists, so the difference of the gray scale corresponding with executing alive polarity averages out, has the observer's of making advantage inconspicuous in element portion Q.

＜B: embodiment 2 〉

Below, embodiments of the invention 2 are described.In addition, in each following form, for effect, function key element similarly to Example 1, pay the symbol identical with above key element, suitably omit the detailed explanation of each.

Fig. 7 means the timing diagram of the action of display unit 100.As shown in Figure 7, during a plurality of units F be divided into respectively first period T1 from the starting point of F during this unit to length preset time, from the warp of the first period T1 second phase T2 (2 decile) of the terminal point of F during this unit later.From sweep signal YA[1 shown in Figure 7]～YA[m] and sweep signal YB[1]～YB[m] waveform can understand, scan line drive circuit 32 is selected each of m the first scan line 12A successively at first period T1, select successively each of m the second scan line 12B at second phase T2.

Fig. 12 means the block diagram of electric structure of the display unit 100 of the embodiment of the present invention 5.As shown in figure 12, each display element E in element portion Q is corresponding with any one in a plurality of demonstration looks (red (R), green (G), blueness (B)).Namely the display element E corresponding with redness is to observing the coloured light of wavelength corresponding to a side outgoing and redness, the coloured light of green display element E outgoing green, the coloured light of blue display element E outgoing blueness.Each display element E of (3k-2) row is with red corresponding, and each display element E of (3k-1) row is corresponding with green, each display element E of 3k row and blue corresponding (k is natural number).Therefore, 2m the display element E that arranges in Y-direction and homochromy corresponding (striped (stripe) arrangement).But each form that shows the arrangement of look can change arbitrarily.

Same with embodiment 1 or embodiment 2, m the first scan line 12A connects respectively n the first display element E1 that belongs to 2 element row R in 2m scan line 12, connects respectively n the second display element E2 that belongs to 2 element row R at m the second scan line 12B.As shown in figure 12, n the display element E that is connected on public scan line 12 is divided into element group P to be connected to 3 display element E on 3 adjacent holding wires 14 (namely with red, green and blue 3 corresponding display element E) as unit.By controlling 3 the display element E gray scale separately in each element group P, show the image of polychrome at element portion Q.

Signal-line driving circuit 34 has a plurality of (n/3) distributor circuit 35 that configures at every adjacent 3 holding wires 14 (each element group P that namely arranges at directions X).As shown in figure 13, distributor circuit 35 (demultiplexer, Port Multiplier) comprises input point N and 3 switch SW (SWR, SWG, SWB).Input point N is supplied with original signal S0.Original signal S0 specifies the voltage signal of 1 system of the gray scale (applying voltage) of 3 display element E belonging to an element group P with timesharing.Distributor circuit 35 each conducting of 3 switch SW (SWR, SWG, SWB), is distributed to 3 systems to original signal S0 in order.Each of the signal of 3 systems that signal-line driving circuit 34 distributes according to distributor circuit 35 generates the data voltage X of 3 systems corresponding with element group P, and each holding wire 14 is exported.

Figure 14 means the timing diagram of the action of display unit 100.In addition, the part of Figure 15 (A) and part (B) are the schematic diagrames that the displaying contents of each display element E in F during the constituent parts that f is individual and (f+1) is individual is represented together with executing alive polarity.As shown in figure 14, scan line drive circuit 32 select successively 2m scan line 12 (alternate selection the first scan line 12A and the second scan line 12B) action similarly to Example 1.

And signal-line driving circuit 34 is between the selecting period of selecting the capable scan line 12 of i in H, action according to each distributor circuit 35, generate to specify the data voltage X[1 of the n system of the gray scale (applying voltage) that is connected to n display element E on this scan line 12]～X[n], each holding wire 14 is exported.The mark of Figure 14 " GA_R " means that the magnitude of voltage of data voltage X is set as the magnitude of voltage corresponding with the gray scale of the pixel of the redness (R) of the first image GA.Equally, " GA_G " means the magnitude of voltage corresponding with the gray scale of the pixel of green, and " GA_B " means the magnitude of voltage corresponding with the gray scale of the pixel of blueness.In this form, satisfy the mode of following condition according to the alive polarity of executing of display element E, setting data voltage X[1]～X[n] polarity.In addition, as shown in the part (A) and part (B) of Figure 15, each display element E executes the alive polarity point that F puts upside down during constituent parts similarly to Example 1.
