본 발명은 제1 텍스처 표면(1)이 디스플레이 소자를 대향하도록 구성된, 디스플레이 표면(7)을 갖는 디스플레이 소자(20) 및 제1 텍스처 표면(1)을 갖는 커버 유리 시트(30)를 포함하는 디스플레이 장치(10)에 관한 것이다. 제1 텍스처 표면(1)은 12 mm의 평가 길이에서 그리고 차단 파장이 0.8 mm인 가우스 필터를 이용하여 측정한 경우 0.12 ㎛ 이상의 제1 산술 진폭 값(Ra1)(Ra1 ≥ 0.12 ㎛) 및 45 ㎛ 이상의 제1 간격 값(Rsm1)(Rsm1 ≥ 45 ㎛)에 의해 규정된 표면 거칠기를 갖는다. 제1 텍스처 표면은 제1 텍스처 표면의 접촉 면적의 적어도 일부에 걸쳐 디스플레이 표면과 직접 접촉한다. A display device with a display element having a display surface and a cover glass sheet, having a first textured surface, such that the first textured surface is facing the display element. The first textured surface has a surface roughness defined by a first arithmetic amplitude value, Ra1, being equal to or greater than 0.12 μm (Ra1≥0.12 μm) and a first spacing value, Rsm1, being equal to or greater than 45 μm (Rsm1≥45 μm) both measured on an evaluation length of 12 mm and with a Gaussian filter of which the cut-off wavelength is 0.8 mm. The first textured surface is in direct contact with the display surface over at least a portion of a contact area of the first textured surface.
