Abstract: PROBLEM TO BE SOLVED: To realize an AC drive while suppressing the voltage loss of a picture signal to be written in respective pixels. SOLUTION: A panel 0 is a panel in which display cells provided with column shaped signal electrodes Ys and plasma cells provided with row shaped discharge electrodes As and Ks are overlapped with each other an matrix shaped pixels 11 are provided at parts in which respective signal electrodes Ys and respective discharge electrodes As and Ks intersect. A scanning circuit 22 successively selects pixels 11 for every row by exciting plasma discharge while successively applying a discharge pulse to respective discharge electrodes Ks. A signal circuit 21 writes a picture signal in pixels 11 of the successively selected row by applying the picture signal to respective signal electrodes Ys. At this time, the circuit 21 performs the so-called column inverting drive by applying a picture signal having an opposite polarity for every one line or plural lines of adjacent signal electrodes Ys. The circuit 22 repeats the successive selection of pixel rows for every prescribed frame periods and the circuit 21 inverts the polarity of the picture signal to be applied to the respective signal electrodes Ys for every frame period.

Abstract: PROBLEM TO BE SOLVED: To simplify the structure on the plasma cell side of a plasma address display device and to increase the effective voltage applied on the liquid crystals on a display cell side. SOLUTION: The plasma address display device has a laminated structure obtained by superposing the display cells 1 having column-like signal electrodes Y and the plasma cells 2 having row-like discharge channels parted from each other by partition walls 7 on each other. The respective discharge channels are allocated with a pair of the discharge electrodes X coated with insulating films. Discharge voltage is sequentially impressed to a pair of the allocated discharge electrodes X and a plasma discharge is excited by utilizing the dielectric characteristic of the insulating films 6, by which the linear sequential scanning of the plasma cells 2 is executed. The signal voltage is impressed to the respective signal electrodes Y of the display cells 1 in synchronization with the linear sequential scanning, thereby image display is carried out. One piece of the discharge electrodes X is disposed under one piece of the partition wall 7 and emerges to both sides thereof. This discharge electrode X is commonly used by the two discharge channels parted from each other by the partition wall 7. The insulating film 6 covering one of the discharge electrodes X allocated to the respective discharge channels is formed thinner than the insulating film 6 covering the other.

Abstract: PURPOSE: To provide a panel structure which does not reveal display defects on a screen even if air bubbles arise in liquid crystal cells. CONSTITUTION: This display panel consists of the liquid crystal cells consisting of a pair of glass substrates 1, 2 arranged to face each other via a spacing and liquid crystals 3 held in this spacing as a basic structure. Each liquid crystal cell is segmented to an effective screen region 5 and a non-screen region 6. The effective screen region 5 has a spacing of a specified size regulated in order to display images. The non-screen region 6 exists on the periphery of this effective screen region 5. The non-screen region 6 is provided with an air bubble capturing part 7 having a spacing of the size larger than the size of the specified spacing of the effective screen region 5. If the air bubble is generated in the liquid crystals 3 existing in the effective screen region 5, this air bubble is moved by surface tension to the capturing part of the non-screen region 6 and is fixed there. Then, the display defect occurring in the air bubble does not appear in the effective screen region 5.
