An etching composition for a silver-containing thin film, the etching composition comprising an inorganic acid compound, a sulfonic acid compound, an organic acid compound, a nitrate, a metal oxidizing agent, an amino acid compound, and water.

Etching composition for thin film containing silver, method for forming pattern and method for manufacturing a display device using the same

A display device may include first and second base substrates, a pixel, a signal line, a pad electrode, and an electronic circuit connected to the pad electrode. The first base substrate includes a first planar surface and a first side surface, which is connected to the first planar surface and extends in a first direction. The second base substrate includes a second planar surface, which is disposed to face the first planar surface in a second direction crossing the first direction, and a second side surface, which is connected to the second planar surface and extends in the second direction. The pixel is disposed between the first and second base substrates. The signal line is disposed on the first base substrate and connected to the pixel. The pad electrode is disposed on the first side surface and connected to the signal line.

Display device having an inclined side surface

A display device includes a light source which emits a light and a display panel which displays an image using the light. The display panel includes a first substrate, a second substrate spaced apart from the first substrate, a plurality of pixels disposed between the first and second substrates, and a light guide layer disposed between the first substrate and the pixels. The light guide layer includes light tunnels which receive the light from the light source and a refractive layer which covers the light tunnels.
