Abstract

The purpose of the present invention is to prevent forming of soot like black substance on the back of the TFT substrate of resin during laser ablation to separate the glass substrate from the TFT substrate. The present invention takes the following structure to counter measure the above problem. A display device having pixels formed on a first surface of the resin substrate including: a first layer, formed from nitride, being formed on a second surface of the resin substrate, the second surface being an opposite surface to the first surface, in which a second layer, which is a separation layer, is formed on the first layer.
