Liquid crystal display device and electronic device

An electronic device, comprising:

• a liquid crystal display device that includes:
• a first substrate that includes a microlens corresponding to each pixel;
• a second substrate that faces the first substrate;
• and
• a liquid crystal material layer sandwiched between the first substrate and the second substrate, wherein
• a first transparent material layer is in the first substrate and includes a material that has a first refractive index,
• a material that has a second refractive index different from the first refractive index is in a portion of the first transparent material layer corresponding to a region between adjacent pixels,
• a second transparent material layer is in the second substrate and includes a material that has a third refractive index,
• a material that has a fourth refractive index different from the third refractive index is in a portion of the second transparent material layer corresponding to the region between the adjacent pixels,
• a third transparent material layer is on the first transparent material layer in the first substrate and includes a material that has a fifth refractive index higher than the second refractive index,
• the material that has the second refractive index is embedded in a first groove,
• the first groove is in portions of the first transparent material layer and the third transparent material layer corresponding to the region between the adjacent pixels, and
• the adjacent pixels include the pixel.
