Abstract: The present disclosure relates to an optical laminate or a reddening-resistant layer. The present disclosure can provide an optical laminate that does not cause a so-called reddening phenomenon even when driven or maintained under extremely harsh conditions (e.g., very high temperature conditions), or a reddening-resistant layer applied thereto.
