Abstract

The present invention provides one kind of planar display with non-matrix blocking structure. The non-matrix blocking structure includes main blocking structure and auxiliary blocking structure, the main blocking structure has interval and main space corresponding to pixel area, and the auxiliary blocking structure is corresponding to the interval of the main blocking structure. Each of the intervals corresponds to scanning line or signal line. Each of the main spaces is connected to at least one interval, and each of the intervals connects two adjacent main spaces.

Description

technical field [0001] The present invention relates to a flat panel display, in particular to a flat panel display with a non-matrix light shielding structure. Background technique [0002] A liquid crystal display (liquid crystal display, LCD) is currently the most widely used type of flat panel display, which has the characteristics of low power consumption, thin and light weight, and low voltage driving. Generally speaking, in a liquid crystal display, a liquid crystal layer is sandwiched between two transparent substrates (such as glass substrates), and driving elements such as thin film transistors (thin film transistors (TFTs)) are disposed on one of the transparent substrates. In a display area of ​​a liquid crystal display, an array of pixel areas is defined by horizontally extending scanning lines and vertically extending signal lines. Each pixel area has a thin film transistor and a pixel electrode. [0003] Figure 19 It is a sectional view showing a convention...
