Claim:
1. A display apparatus comprising: a backlight assembly which generates a light; and a display panel which receives the light to display an image, the display panel comprising: a first substrate; a second substrate which faces the first substrate and is disposed closer to the backlight assembly than the first substrate; a gate line disposed on the first substrate; a data line disposed on the gate line and insulated from the gate line; a thin film transistor disposed on the first substrate and electrically connected to the gate line and the data line; and a reflection preventing layer which is disposed between the first substrate and the gate line, and the reflection preventing layer reducing an amount of a reflected light reflected by the gate line, wherein the reflection preventing layer comprises a first sub-layer which is disposed on the first substrate and has a first refractive index, and a second sub-layer which is disposed between the first sub-layer and the gate line, and has a second refractive index which is greater than the first refractive index, and wherein the reflected light is an external light reflected by the gate line, and a thickness of the first sub-layer and a thickness of the second sub-layer are obtained based on following equation, d1 denotes the thickness of the first sub-layer, d2 denotes the thickness of the second sub-layer, λ denotes a wavelength of the external light, n
