In this way, since the pressure difference between the second electrode 120 and the third electrode 130 is small during the first polarity period (N), the characteristic of high light transmittance can be maintained. In addition, since the pressure difference between the second electrode 120 and the third electrode 130 is large during the second polarity period (N + 1), it has a characteristic of rapid response. In summary, the present invention adopts the design with different pressure differences between the electrodes between the different timings, so that the display panel 100A simultaneously has the characteristics of high light transmittance and fast response.
