In conjunction with above-mentioned explanation of powering up about how for the second electrode structure 42 of being arranged on second substrate 12 inboards, can be clear and definite, optional, the second substrate inboard can arrange and the inboard identical driving circuit of first substrate, powers up to give the second electrode structure 42; But preferred, be to utilize conducting resinl that the electrode of same kind in the first electrode structure and the second electrode structure is electrically connected, so just need not to set up driving circuit at second substrate.
Need to prove, in the display panels of two kinds of electrode structures, the first electrode structure can be identical with the second electrode structure before the including of above-mentioned introduction, also can be different.Be preferably in embodiments of the present invention, the first electrode structure and the second electrode structure all adopt the electrode structure of IPS escope in a display panels, or all adopt the electrode structure of ADS escope; Further preferred, in the first electrode structure in the adjacent stripes spacing of same layer and the second electrode structure adjacent stripes spacing of same layer consistent in the same area (echo area or transmission area); Further preferred, the first electrode structure and the second electrode structure are symmetrical about the mid-plane of liquid crystal layer, like this, can not affect the light transmission rate of described display when reducing driving voltage.
