    Abstract: The display device includes: an array substrate having an in-cell polarizing layer and a color layer; a counter substrate; a liquid crystal layer; a white light source; and a polarizing plate placed on the counter substrate on its one side opposite to a side on which the liquid crystal layer is provided. The color layer includes a red color layer, a green color layer and a blue color layer. The red color layer includes a red color filter and a red wavelength conversion layer which is located on its one side closer to the white light source than the red color filter. The green color layer includes a green color filter and a green wavelength conversion layer which is located on its one side closer to the white light source than the green color filter. The blue color layer includes a blue color filter.

    Abstract: In the case of a pixel including four and more sub pixels, the area of one pixel is larger than that in the case of a pixel including three sub pixels; therefore, high definition becomes difficult. When a central display area has a structure of four and more sub pixels, in a display device, the pixel structure in a peripheral display area for use in creating a virtual image is reduced to three sub pixels, to allocate the vacant space for high density assignment. Only the pixel density in the vicinity of a frame of a lens portion is compressed, in order to apparently resolve the discord with the image of a non-lens portion. The pixel side in the peripheral display area may be even or gradually narrowed.

    Abstract translation: 在包括四个以上子像素的像素的情况下，一个像素的面积大于包括三个子像素的像素的情况; 因此，高分辨率变得困难。 当中央显示区域具有四个以上子像素的结构时，在显示装置中，用于创建虚像的周边显示区域中的像素结构被减少为三个子像素，以分配用于高密度的空白空间 分配。 只有透镜部分的框架附近的像素密度被压缩，以便明显地解决与非透镜部分的图像的不一致。 周边显示区域中的像素侧可以平均或逐渐变窄。
