An XY matrix type liquid crystal display panel having a plurality of X electrodes aligned at a given interval in one direction, a plurality of Y electrodes alinged at a given interval in a direction normal to the one direction and a layer of liquid crystal composition disposed between the X and Y electrodes. While an electrode layer forming the Y electrodes is shaped connect divided picture element electrodes, the counterpart forming the X electrodes is arranged to confront with two or more picture element electrodes along the Y axis. Further, each of the Y electrodes is divided into two along the Y axis. A contact area of each of the divided by two Y electrodes extends toward two opposing ends of a support where the Y electrodes are disposed. In a preferred form, the matrix type liquid crystal panel comprises two or more layers of liquid crystal composition and the X and Y electrodes are so arranged that electric field-responsive operating regions of the respective liquid crystal composition layers never are overlapped with one another.

A thin film transistor comprises a substrate, a gate electrode, a drain electrode, a source electrode, an insulative layer, and a semiconductor layer for the purpose of switching display signals to be applied to at least one display element of a display device. Preferably, the thin film transistor is mounted on the same substrate on which the display element is mounted. The selected material for the display element electrode is identical to at least one selected from the gate electrode, the source electrode, and the drain electrode. In another aspect of the present invention neither the gate electrode nor the insulating layer overlap either of the drain electrode or the source electrode. A resistance value of the semiconductor layer between the source and the drain electrodes is considerably less than the resistance value of the semiconductor channel layer controlled by the gate electrode. For this purpose, at least one of the width, thickness, and impurity concentration is varied therebetween. In a further aspect, the semiconductor channel has a substantial length more than the distance between the source electrode and the drain electrode with the help of a labyrinth passage.

An electrode structure on a matrix type liquid crystal display panel includes M column electrodes and N row electrodes both of which cross each other at a right angle to define picture elements via a layer of liquid crystal material. The matrix shaped electrode structure is such that a third picture element C (X.sub.m ', X.sub.n ') is located between a first picture element A (X.sub.m, Y.sub.n) and a second picture element B (X.sub.m+1, Y.sub.n+1), wherein 1.ltoreq.m.ltoreq.M and 1.ltoreq.n.ltoreq.N, thus enhancing resolution in vertical and horizontal directions. A diamond shape is exemplary of the possible shapes of the picture elements wherein each pair of the diagonally disposed corners are connected to that of their adjacent elements.
