Problems solved by technology
As a result, the liquefaction path of the liquid crystal in the non-display area 70 also becomes smaller, and the injection speed decreases, thereby causing a serious problem that the injection time is significantly increased.
[0007] As the size of the liquid crystal display increases, the number of pixels also increases, and the adverse effect of the small gap h1 in the non-display area 70 also increases.
Sometimes it is difficult to inject the liquid crystal as a whole into the liquid crystal display device

Abstract
A liquid crystal display apparatus is produced by the steps of arranging pixel electrodes, TFT devices and signal wiring on one surface of one substrate, arranging a transparent layer on a portion of one surface of a transparent substrate which portion is to be a display portion, bonding the one substrate and the transparent substrate to each other while the one surface having the pixel electrodes formed thereon faces the one surface having the transparent layer formed thereon, and injecting a liquid crystal between the substrates to form a liquid crystal layer. A fluidization path of the liquid crystal can be secured in a non-display portion, too, in which the TFT devices and the signal wiring are disposed when the liquid crystal is injected. Therefore, it is possible to shorten the injection time by increasing the liquid crystal injection speed and to improve productivity.
Description
technical field [0001] The invention relates to a liquid crystal display device and a manufacturing method thereof. Background technique [0002] A liquid crystal display device is a kind of liquid crystal layer sandwiched between a pair of substrates to apply a voltage to change the direction of the liquid crystal molecules, and to display black and white by changing the light transmission performance of the liquid crystal layer due to the change of the molecular direction. or a display device of color characteristics or images. [0003] attached Figure 40 It is a cross-sectional view showing an enlarged structure of a monochrome liquid crystal display device 5 in the background art. [0004] The liquid crystal display device 5 includes a reverse substrate 51 , a transparent substrate 60 , and a liquid crystal layer 57 formed by injecting liquid crystal between the reverse substrate 51 and the transparent substrate 60 . On the transparent substrate 60 are formed a shield...
