The present invention relates to a glass display board, and in particular, to form a structure having a cavity and a space bar function in one chemical etching process and to form a separate electrode for each cavity to reduce the number of processes and to enable blinking for each cavity The present invention relates to a glass electroluminescent plate by chemical etching and a method for producing the same, which are suitably described below.

In general, a glass display board is a panel sign product made of a glass plate that emits phosphors by ultraviolet rays generated by a gas discharge in a predetermined space.

Therefore, the glass board is used by bonding two pieces of electrode glass of the upper plate and the lower plate, and the panel freely expresses the character or image to be expressed.

In addition, the glass display panel using PDP (Plasma Display Panel) technology makes a vacuum between two sheets of thin glass plate coated with fluorescent material, and puts special gas into it, and converts electrical energy into light energy to emit light.

The discharge has a fluorescent layer coated with a fluorescent material inside the cavity, the inert discharge gas is injected / charged, and emits ultraviolet rays, so the brightness is excellent and environmentally friendly when mercury is not used.

Here, the plasma refers to a fourth material state in which a gas state is separated into electrons having a negative charge and positively charged ions at a high temperature, and the charge separation degree is very high, but the neutral and negative number of charges is the same. Currently 99% of the universe is known as plasma. Fluorescent lights, neon lights, auroras and lightning are typical of plasma states.

At this time, the cavity 40 is formed by chemical etching, and the inter-cavity passage 41 is formed. The intercavity passage 41 is formed by not applying the photoresist 20 on the lower plate glass 10. Since the etched surface is smooth, no indication occurs even when the inter-cavity passage 41 is formed. Thus, since the cavity 41 is formed, the exhaust time is not a problem at all.

Then, after the chemical etching, the photoresist 20 is removed to complete the cavity 40 and the space bar 30 in the lower plate glass 10.
