Abstract: A transparent display apparatus includes a liquid crystal cell and a Sight source opposite to a side surface of the ceil. The cell Includes a first substrate, first electrodes on the first substrate, a second substrate, a second electrode on the first or second substrata, a liquid crystal layer between the two substrates, signal lines on the first substrate, and a light-shielding pattern on the second substrate. The layer is configured to totally reflect or scatter light from the light source incident to a region, opposite to a first electrode, due to action of an electric field provided by the first and second electrodes. At least one signal line has a bottom surface and a light-reflecting side surface facing the light source, and a slope angle therebetween is acute. The pattern is located in a reflection path after a portion of the light irradiates the light-reflecting side surface.
